* [PATCH] unexec() for Cygwin, try #3

From: Joe Buehler @ 2004-03-31 12:52 UTC (permalink / raw)


- code formatting fixed
- debugging printf's conditionalized and off by default
- added support for Xaw3d scrollbar widgets
- strcasecmp instead of strcmp for .exe suffix
- added comment about object ordering for link (comment from Stephan Monier)

Please install in CVS for me, I don't have write access (and given how
little I know about CVS, it would be somewhat dangerous to give it to me...)

Today I tried your patch and _all_ worked fine on cygwin except
patching of the ChangLog files. I crosschecked too building of the W32
version with the gcc mingw port and under GNU/Linux. Here too all
worked fine. So I assume installing of the patch would be fine.
