upstream glibc is making trouble again

[Chip Coldwell]

I'm having problems building emacs against glibc-2.6.90-4 (Fedora
8/rawhide GNU/Linux distribution).  Here's the relevant section of the
build log:

gcc -c -D_BSD_SOURCE   -Demacs -DHAVE_CONFIG_H -DUSE_GTK  -I. 
-I/builddir/build/BUILD/emacs-22.1/src -D_BSD_SOURCE -I/usr/include/gtk-2.0

-I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include

and a link to a discussion that seems relevant also:

Quoting:

It includes <fcntl.h>, which provides open, and POSIX allows functions
to be defined as function-like macros.  Until recently glibc didn't
define open as a function like macro, but in glibc 2.6.90 and later it
does when -D_FORTIFY_SOURCE=2, to enforce correct use of
open/open64/openat/openat64.

Any suggestions for a fix?
