Sorry about the large email: didn't realize how big it was when I cut
and pasted.
Line 108 is indeed:

int     _EXFUN(pipe, (int __fildes[2] ));

I've greped around for "define pipe" and the only results I could find
are /usr/include/glib-1.2/glib.h and
/usr/include/glib-2.0/glib/gwin32.h. Both files define precisely the
method you mention:

#define pipe(phandles)	_pipe (phandles, 4096, _O_BINARY)

Here's the kicker: I commented out both instances of that #define and
the build still fails with the same error. Is there anyway I can find
out precisely where the preprocessor is getting that method? C really
isn't my thing so when I have problems like this with prerequisite
packages, I'm really at a loss. Thanks everyone for lending me a hand
with this!
