Subject:	RE: c++/4479 can't build gcc-3.0.1 under cygwin

I suspect we are all right :->

I have just built gcc-3.0.1 (release) using snapshot cygwin1.dll and headers
on win2k.  I know it works with previous cygwin releases (but I forget which
ones).

Your build (and others) with current cygwin release fails, and trying
snapshot cygwin1.dll only failed.  Points to a recently introduced header
problem, as you indicate.

I haven't reproduced your problem today (although I saw it on another PC of
mine), but it has been solved by:
 * stepping back to a previous cygwin release (forget which),
 * stepping forward to snapshot cygwin1.dll + headers
 * patching libiberty so that gcc-3.0.2 will work (done by cgf)
 * your work around below

If you are happy I will close the PR.

#defining HAVE_SYS_ERRLIST and HAVE_SYS_NERR in both libiberty/config.h and,
for bootstrapping, in i686-pc-cygwin/libiberty/config.h allows the build and
install process to complete successfully. I think this evidence clearly
shows that the problem does not lie with the cygwin DLL.

HTH,
Dave
