Let's see what the bug is first.  It could just be an installation messup.
What is the output of this command?

/opt/lsb/bin/lsbcc -E -DHAVE_CONFIG_H -I. -I.. close-stream.c

Not only does POSIX require this, it's longstanding practice; I've
never run into a system where <sys/types.h> didn't define size_t, and
regex.h has assumed that <sys/types.h> defines size_t for years
without running into a problem.

I still suspect an installation error of some sort.
