That compiler costs money.  I'm using gcc distribution supplied on the
free software CD distrubuted with Solaris i.e. the 2.95.2 version.

Because we've never "#define stat ..." and "#define lstat ..." before.

I haven't tried another gcc version.  Must I and must it be on Solaris?

I don't know if it's specific to this setup.  What should I test?

A native Solaris compiler costs money and I don't have one.

This looks promising even though I have Solaris 8 Intel Edition.

        /export/home/cvsusr/ccvs/cvs-1.12/windows-NT:$ gcc -v
        Reading specs from /opt/sfw/lib/gcc-lib/i386-pc-solaris2.8/2.95.2/specs
        gcc version 2.95.2 19991024 (release)

Isn't "usage" controlled by CVS make process or did I misunderstand?

I choose a broken gcc as the likely culprit. I'll run a test and report.
