>Description:
GCC-3.0 doesn't build under Cygwin out of the box. After running configure, you must patch line 224 of install.sh to add the .exe extension as follows:

 dsttmp=$dstdir/#inst.$$#.exe
                         ^^^^

A better patch could probably be made which detects Cygwin and automatically makes this adjustment, but I don't know how to do that.

One other fact, which probably has no specific relevance to Cygwin: if you install gcc using --with-prefix=... (so that you don't disturb your existing 2.95.x installation), you get an advisory about the requirements for linking. This advisory is generated by a section of ltmain.sh starting at
line 4892. Unfortunately, it comes in the middle of a huge amount of other make output which is probably best ignored. I installed GCC-3.0 twice before I noticed the advisory, and by the time installation was finished it had scrolled out of my buffer and was lost forever. I noticed enough to see that I could add "-L/usr/lib" to get things to link. If anyone knows how I can recover the complete information I'd love to know it. In any case I think it should be considered a bug that important advisories don't come at the end of the make process.

Download gcc-3.0
