Re: My attempt to build gcc-3.0 failed :-(

["Tim Prince" <tprince at computer dot org>]

Unless you know good reasons to do otherwise, the standard cygwin
installation is far better than the usual one size fits all.  As we
pointed out, it's not cygwin per se which has trouble with NAI; all gzip
family and many other styles of compressed files produce false
positives.

If you don't understand the prefix systems of gcc and cygwin, you're
better off letting it default to /usr/local.  Cygwin builds of gcc 3.x
follow fairly closely the standard advice on the gcc web pages.  You
might want to stick with options which have worked for others,
like --enable-sjlj-exceptions (I also use --with-included-gettext, as it
seems to help on my installation, and --enable-languages='c++,f77' as
those (c implied as well) are supported on cygwin.  You should copy
/usr/include to the include directory implied by --prefix
(/usr/local/include for default) befor configuring.

I don't see any great attraction in gcc-3.0.1, as it has a few serious
performance regressions compared to 2.95.3, but it is a step forward in
g++.  AFAIK 3.0.1 and 3.1 build the same way, and I find 3.1 impressive
with its better performance (particularly with 8- or 16-byte alignment
set in binutils) and beginnings of ability to do -msse for P4 (also
dependent on updating binutils), and far better reliability than 3.0 had
until near release.
