Appologies for the mis-communication.  I only have access to Linux,
BSD and Unix boxen, and only checked on a glibc box.

Again, appologies for confusing the issue.  I had presumed that cygwin
would have used glibc, but I see from their cvs that they in fact use

They added getdelim(3) getline(3) to stdio.h in:


and as you can see from that diff w/o protecting them in an #ifdef.

The full annodation of their stdio.h in:


shows that they remain unprotected.

So, even though glibc protects the declaration unless the proper
#define is used, other libcs may not.  And cygwin’s version of
newlib is one such example.

(I hope this proves more useful than my first reply....)
