Now that I'm not hanging off a GPRS connection, I can search: I seem to be bumping into the same / a related issue to the following: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=492817 http://gcc.gnu.org/ml/gcc/2001-09/msg00032.html http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36505 Although it's in the debian bug database, I'm using the vanilla GCC 4.3.1 tarball. Should I file a PR or is it PEBKAC? If it isn't just me being a n00b and misconfiguring GCC, what's the easiest / most standards-friendly workaround? I'm tempted to just s/include_next/include/ in the installed C++ headers for now. Pinski's comment on #36505 seems to suggest it's PEBKAC... but where am I supposed to get /usr/include/stddef.h? The system is fairly old and is based on some 2001 Debian, and has glibc 2.3.1 IIRC. Sigh... I'm *really* not in the mood for building glibc.
