I just recently discovered tests for watcom in the Build.sh script
Naturally curious as I am, I started to play with trying to compile mksh with openwatcom on Linux (Arch x86_64) - mostly due to nostalgia with all the Dos4GW games etc... curious to see how small/performant openwatcom can make a real modern program compared to GCC.
It seems like the tests choke on a number of places (preprocessor does not successfully identify watcom etc...). and the libc bundled with openwatcom does not contain some headers that seems to be needed.
Are there any tricks to get through the Build.sh? Or is the watcom support abandoned? There seems to be a lot of warnings during the tests...
For reference, I attach my modified PKGBUILD (modified from the officially distributed variant of mksh in Arch linux) that I use for my compilation tests.
