bug in libgendep? syscall fork

Hi all,

I'm developing a quite interesting free software using libgendep.
Now I think I have an important problem. I think that the wrapper of libgendep, syscall.c, does not detects all calls to open. And I wonder why?

If I do:
strace -f gcc Simplescript.c -o project 

I can find lots and lots of calls to open that libgendep does not detects :(.
I print every file directly from syscall.c but there are some opens that they don't appear.

I have been investigating the trace of strace and I see that lots of open calls are created in fork processes, so...maybe the problem is this.
Do you know if syscall(SYS_open,.... also searches opens of child processes??

Thanks so much
