I maintain `unifdef`, which is not a complicated program to port but it
does require some platform-specific stuff on Windows (partly because of
the poor standards conformance of the Windows C library). There's a fun
rule that `unifdef` must contain no #ifdef (or #if etc.) so the
portability stuff is handled by the build scripts adjusting the include
path and list of object files. Not a very scalable solution :-)

moderate, becoming slight later. Showers, thundery in east. Good, occasionally
moderate.
