You should probably define _REENTRANT as well, e.g.
gcc -D_REENTRANT -o foo foo.c -lpthread
so you get a per-thread errno and thread-safe "*_r" functions
(getlogin_r(), gethostbyaddr_r(), gethostbyname_r(), and many others).
See the "Feature Test Macros" section of the glibc manual, and of
course the "POSIX Threads" section for all the gory details.
