This will help a great deal as I pursue troubleshooting failed C compiles. The easiest way to build is using cygport - you need to provide only the minimum necessary definitions in your .cygport script, and run: $ cygport *package*.cygport get prep to download and patch sources, and run: $ cygport *package*.cygport all to compile, build, stage, and package for Cygwin. To apply patches, edit sources under pkg-ver-rel.arch/src/..., diff edited files against files under pkg-ver-rel.arch/origsrc/... to generate each patch, and add to the PATCH_URI list in each cygport. This allows you to reuse your patches on later releases, or submit them upstream, so you do not need to apply them to later releases. -- Take care.
