Hello.

I discovered that tests/cygnus/tgen doesn't build either.
So I tried to fix that up. I already had a fix in there for the C++-ness
of some of the programs. But the recent crt0 changes seem to have broken
that too. I get the following build error:

gpp -nostdlib -L../../../lib -o gacosvec.exe gacosvec.o ./qfloat/qfloatx.a ../../../lib/crt0.o ../../../lib/libm.a c:/djgpp/lib/gcc-lib/djgpp/3.21/libstdcxx.a -lc c:/djgpp/lib/gcc-lib/djgpp/3.21/libgcc.a
c:/djgpp/lib/gcc-lib/djgpp/3.21/libgcc.a(unwind-dw2-fde.o)(.text+0x230): multiple definition of `___register_frame_info'
../../../lib/libc.a(rfinfo.o)(.text+0x0):rfinfo.c: first defined here
collect2: ld returned 1 exit status
make.exe: *** [gacosvec.exe] Error 1

Any ideas?

This seems weird, because I don't think the recent crt0 changes
have done anything that would change __register_frame_info's usage
by crt0. A quick nm and grep shows that it is used by 2.03 & CVS's crt0
and is present in 2.03 & CVS's libc. Bizarre.

Anyway, below is my current patch for makefiles under tests/cygnus.

Thanks, bye, Rich =]
