I don't see how that patch could fix the issue for GCC 3.1, since it simply 
changes a test to check for GCC 3.4 instead of 3.3, so GCC 3.1 should behave the 
same regardless of whether the patch is installed.

The only instance of '__GNUC_PREREQ (3, 3)' is the one in lib/cdefs.h, so I 
assume that's the only thing causing you problems. The '__GNUC_PREREQ (3, 3)' 
comes straight from glibc misc/sys/cdefs.h (installed as 
/usr/include/sys/cdefs.h on my platform). So if there's a problem here, 
presumably the problem is also in current glibc.

Can you investigate why current glibc's approach does not work for you, whereas 
old-fashioned glibc does? For example, what does /usr/include/sys/cdefs.h look 
like on these older platforms, and why do their definitions of __THROW work when 
Gnulib's doesn't?

As Bruno says, these ancient systems are low priority for Gnulib, but if we know 
why the fix is a good one we can install it (and I assume propagate the fix back 
to glibc....).
