Hello.

Some of the C++ programs in tests/libc fail to build. Namely,
tests/libc/dos:

bash-2.04$ pwd
c:/develop/djgpp.rw3/tests/libc/dos
bash-2.04$ make
gcc @../../gcc.opt -I. -I- -I../../../include  -c echome.c
ld  ../../../lib/crt0.o echome.o ../../../lib/libc.a -o echome.exe c:/djgpp/lib/gcc-lib/djgpp/3.32/libgcc.a -T c:/djgpp/lib/gcc-lib/djgpp/3.32/djgpp-x.djl
gcc @../../gcc.opt -I. -I- -I../../../include  -c ff.c
ld  ../../../lib/crt0.o ff.o ../../../lib/libc.a -o ff.exe c:/djgpp/lib/gcc-lib/djgpp/3.32/libgcc.a -T c:/djgpp/lib/gcc-lib/djgpp/3.32/djgpp-x.djl
gpp @../../gpp.opt -I. -I- -I../../../include  -c ffxx.cc
ld  ../../../lib/crt0.o ffxx.o ../../../lib/libc.a -o ffxx.exe c:/djgpp/lib/gcc-lib/djgpp/3.32/libgcc.a -T c:/djgpp/lib/gcc-lib/djgpp/3.32/djgpp-x.djl
ffxx.o(.eh_frame+0x11):ffxx.cc: undefined reference to `__gxx_personality_v0'
make.exe: *** [ffxx.exe] Error 1
rm echome.o ff.o ffxx.o

Below is a start on fixing this. It duplicates some of the fixes
we made under src/ for building C++ files.

I'll add this to the to-do list.

Bye, Rich =]
