  That's because it was written for Sun's C compiler and not gcc, and Sun uses
Sun's C compiler and Cygwin uses gcc.

  Yep, gcc understands different command-line options from Sun's compiler.
This isn't a Sun mailing list, so there's no guarantee anyone round here will
know what those are supposed to do.

  Yep, there's a good reference, it's called 'TFM'.  Read the docs for the Sun
compiler, see what those options do, read the docs for gcc, see how to achieve
equivalent effect using options for gcc, edit the makefile to replace the one
by the other.

  Docs for gcc can be called up on cygwin using "info gcc".  I don't know what
documentation system your Sun uses but "man cc" is almost bound to work.
