/* This file declares various DWARF-related constants using a set of
macros which can be redefined by the including file.
The macros are in sections. Each section corresponds to a single
set of DWARF constants and has a corresponding key. The key is
used in all the macro names.
The sections are TAG (for DW_TAG_ constants), FORM (DW_FORM_), AT
(DW_AT_), OP (DW_OP_), ATE (DW_ATE_), and CFA (DW_CFA_).
Using TAG as an example, the following macros may be used for each
key:
DW_FIRST_TAG(name, value) - Introduce the first DW_TAG constant.
DW_TAG(name, value) - Define a subsequent constant.
DW_TAG_DUP(name, value) - Define a subsequent constant whose value
is a duplicate of some other constant. Not all keys use the _DUP
macro form. If more than one name shares a value, then the base
(DW_TAG) form will be the preferred name and DW_TAG_DUP will hold
any alternate names.
DW_END_TAG - Invoked at the end of the DW_TAG constants. */

The libbacktrace library
Initially written by Ian Lance Taylor <iant@golang.org>
The libbacktrace library may be linked into a program or library and
used to produce symbolic backtraces.
Sample uses would be to print a detailed backtrace when an error
occurs or to gather detailed profiling information.
In general the functions provided by this library are async-signal-safe,
meaning that they may be safely called from a signal handler.
That said, on systems that use dl_iterate_phdr, such as GNU/Linux,
the first call to a libbacktrace function will call dl_iterate_phdr,
which is not in general async-signal-safe. Therefore, programs
that call libbacktrace from a signal handler should ensure that they
make an initial call from outside of a signal handler.
Similar considerations apply when arranging to call libbacktrace
from within malloc; dl_iterate_phdr can also call malloc,
so make an initial call to a libbacktrace function outside of
malloc before trying to call libbacktrace functions within malloc.
The libbacktrace library is provided under a BSD license.
See the source files for the exact license text.
The public functions are declared and documented in the header file
backtrace.h, which should be #include'd by a user of the library.
Building libbacktrace will generate a file backtrace-supported.h,
which a user of the library may use to determine whether backtraces
will work.
See the source file backtrace-supported.h.in for the macros that it
defines.
As of July 2024, libbacktrace supports ELF, PE/COFF, Mach-O, and
XCOFF executables with DWARF debugging information.
In other words, it supports GNU/Linux, *BSD, macOS, Windows, and AIX.
The library is written to make it straightforward to add support for
other object file and debugging formats.
The library relies on the C++ unwind API defined at
https://itanium-cxx-abi.github.io/cxx-abi/abi-eh.html
This API is provided by GCC and clang.

#
# This file is free software; the Free Software Foundation

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is '.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

Your 'rm' program seems unable to run without file operands specified

the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
