Hello.

I've just been looking at building the test suite with gcc 3.1. Most of the
problems I found were to do with headers not being included (e.g. <string.h>
for strlen()). But the following have no obvious fix to me:

tests/libc/ansi/stdarg/stdarg.c: This needs __dj_va_rounded_size, but it's not
found. Presumably gcc 3.1 uses its own va_*, so we never pull in
__dj_va_rounded_size. Should the test be amended to only use
__dj_va_rounded_size if the gcc version is less than 3?

tests/libc/dos/ffxx.cc: This won't link, presumably because some C++ library
hasn't been linked in. I tried including libstdcxx.a and libsupcxx.a on the
link line, but that didn't seem to help.

tests/libc/go32/signals.c: The following line:

    urand = ((double)rand()) / RAND_MAX;

gives this warning:

gcc @../../gcc.opt -I. -I- -I../../../include  -pg -c signals.c
cc1.exe: warnings being treated as errors
signals.c: In function `int_handler':
signals.c:23: warning: cast does not match function type

I don't understand this. Casting to a long, then a double seems to work. (I
don't have K&R to hand, to help me out.)

tests/libc/go32/makefile: This adds '-pg' to LDFLAGS, which ld from GNU
binutils 2.11.2 chokes on.

tests/libc/pc_hw/farptr/farptr.c: main() does not have argc, argv as usual,
but a weird triplet of values. This looks intentional, but how do you run it?

Bye, Rich =]
