Cygwin support to the RPM scripts. The patch from David did not
apply cleanly and Joel ended up making all the modifications
plus some it should have included for consistency by hand. His comments:
I've included a diff against the last (19991203) snapshot RPM scripts that
adds what I think is required for Cygwin support. Basically all this boils
down to is adding EXE extension support. I've added the AC_EXEEXT rule to
conifgure.in (requires a valid 'cc' to work - this is not available in the
standard Cygwin distro). Each of the *.spec.in have @exe_ext@ includes in
them for each program that results in an EXE. The only odity here is that
the chill driver program is a shell script and thus does not require .exe to
be added... The mk*.in have all been updated to process the new exe_ext
rule.
