This could be a problem.  According to the glibc CVS,
http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/include/unistd.h.diff?r1=1.18&r2=1.19&cvsroot=glibc&f=h,
the type of the 2nd argument changed from int to size_t on 2001/3/21. 
According to the CVS tags, this change was first released in
glibc-2.2.3.

We were able to work around this problem in programs/winhelp by not
including winsock.h, but could this problem crop up anyplace else?  It
seems that it is currently impossible to include unistd.h and winsock.h
on a machine with glibc >= 2.2.3.
