[Tinycc-devel] tcc x86-64 and gawk - progress

[arnold]

Hello All.

Kudos to whoever has been working on the x86_64 port. It now compiles
gawk with only one test failure!  This is significant progress.

The one remaining test failure seems to be related to handling NaN
floating point values.  Here is the diff of the test results.

It would be really cool to have gawk pass all its tests with tcc.

Can someone look at this?  Instructions to replicate:

        git clone git://git.savannah.gnu.org/gawk.git
        cd gawk
        git checkout gawk-4.0-stable    # important!
        ./bootstrap.sh
        ./configure CC=tcc && make && make check

Thanks!
