Getting GCC's testsuite, i.e., dejagnu, under cygwin-1.1.7

These fixes are working here, on W2KSP1.  Thanks.  I've run into addtional
problems which are triggered by g77 -O -march=pentiumpro, and I'm still at a
loss how to track them down. The compilers seem fairly stable without the
pentiumpro option. Would someone be interested if I could show a gcc
translation which replicates an ICE, on both linux and cygwin?

This is probably of interest to other cygwin users.  It is for current gcc
cvs.  I'll write up the -lm problem with g77 for the cygwin list, as it also
occurs with the current cygwin release.


This is how I did it.  Some of the changes are hacks looking for better
solutions.  cygwin needs to be installed in the root directory of the drive
(C:\ or D:\).  This is against the general advise, but is the only known way
to get dejagnu to work.

The g77 execute tests fail as cygwin g77 does not like "-lm".  I removed it
from /usr/share/dejagnu/target.exp.  There is probably a neater way to do
it, but ...

  # This must be added here.

The g++ testsuite will not run as dejagnu cannot exec
${odir_v3}/tests_flags.  Fixed thus.  This has been submitted to

Flags in i686-pc-cygwin/libstdc++-v3/tests_flags are wrong.  (This is a
generated file in the build directory).  Need to patch it thus.
