# This is used by the buildbot to cross-compile for OS/2 from Linux, using

# OpenWatcom. In an ideal world, we wouldn't need this, but we need a few

# things to do this "properly" ...

#

# - OS/2 running as a VMware guest on the build machine

# - Buildbot-worker running on that OS/2 guest

# - CMake for OS/2 that...

# - ... has Open Watcom compiler support and...

# - ... a Watcom WMake project generator.

#

# Some of these things are doable (there is a CMake port for OS/2, you can

# use GCC with it), but since OpenWatcom will just target OS/2 on Linux just

# like it could on OS/2, it's easier and more efficient to just have a

# buildbot script compile it here.

#

# Note that we just blast all the C files through the wcc386 compiler and

# skip CMake entirely. We should fix this at some point.
