I've compared the following check-outs:

a) DJGPP CVS sometime ago - this does not have any of the gcc 3.1-related
commits;
b) DJGPP CVS updated to latest;
c) DJGPP CVS with all my patches.

I rebuilt libm for all the cases with gcc 3.1. Then I ran the test suite. They
all give the same mtest.results file. It can be found here:

    http://www.phekda.freeserve.co.uk/richdawe/djgpp/misc/mtest.results

However, more tests fail than in the std-*.results files in tests/cygnus in
djtst203.zip:

    File                                  Failures
    ----                                  ---
    std-v202.results from djtst203.zip    395
    std-libc.results from djtst203.zip    478
    mtests.results from a), b) or c)      525

I don't think the *scanf() patch has caused an increase in the number of
failures, since the result is the same with and without the patch. So, if
there are no objections, I will commit the patch after waiting the usual week.

Bye, Rich =]
