'Course, for my cygwin-host, mingw-target cross compiler, I'll need to respin it so that it coexists with the official gcc and gcc2 and gcc-mingw packages...sigh.

Do you need this anymore, though?

Perhaps not. It was really just an experiment: everybody including me has been claiming that "just build a real cross-compiler; that's 'the right way to do it'"

so I gave it a shot.

It wasn't as easy as everyone thought. Lots of weirdness (mostly in directory layout) to make it coexist peacefully with the mingw bits of cygwin.

 You could get by with this, couldn't

i686-pc-mingw32-gcc is:
gcc -mno-cygwin $(@+"$@"}


Or, should I not be coopting the i686-pc-mingw32 target directory?
Maybe it really should be something like i686-pc-mingw32-cygwin.  Bleah.

No, I think you made the right choice. Besides, my cross compiler goes into /opt/mingw/* -- so no conflict there. Also, if one were to install mingw itself, it goes into /mingw.

Say, where do you change gcc(2.95.3) so that g++-2 links against libstdc++-2.a instead of libstdc++.a? (Ditto g77). It doesn't seem to be in the specs file, so I dunno WHERE that is done...

It is in the last two lines of the specs file:

#define LIBSTDCXX "-lstdc++-2"
#define FORTRAN_LIBRARY "-lg2c-2"

I'll look for it -- it's not in my "normal" sources, so I guess normal sources use a default definition from somewhere else. I'll download your gcc2-src package and use that...

The files themselves get munged by mknetrel's extra/gcc2 script.

Ah. But if you munge the filenames at install time, then don't stage2 and stage3 break?

Btw, I moved that libstdc++.a.whatever file out of /usr/lib for the next
release.  Although, actually, if I had just moved it into the
/usr/i686-pc-cygwin/lib directory, I might not have had to add the -2
part.  Argh.  Not going to change it now...

Agreed -- I actually LIKE the -2 distinction.

(Who's off for the 4000th rebuild of these packages...)
