1) A question on libc function:
int getopt(int argc, char * const argv[],

The fact that it declares "char * const argv[]" and not
"const char * const argv[]" means that it changes argv ?

2) Is libc containing POSIX functions shipped
with gcc,
No
or it is a completely different project ?
Yes and No... The GNU C library is working only with Linux. Not ported for
Solaris2, AIX, HP-UX, SVR4,... Most platforms provide their own C libraries
and these are proprietary or custom (sources maybe available) ones.
