BTW, why calling it a GNU extension, not GLIBC or LIBC.
>From the man page:  As  an  extension  to  the  POSIX.1-2001 standard,
Linux (libc4, libc5, glibc) getcwd() allocates the buffer dynamically
using malloc(3) if buf is NULL. 

get_current_dir_name() is a GNU extension though, again according to the
man page.
