Building GCC from Sources

If the failure is "gencode" complaining about "unknown rtx code..." then
it's caused by not handling DOS CR LF property. This can be fixed by
doing one of the following:

* apply the patch
	http://gcc.gnu.org/ml/gcc/2001-07/msg02146.html

* mount the directory the sources are under in textmode

* convert the file gcc-3.0/gcc/config/i386/i386.md to use Unix newlines
	http://www.cygwin.com/ml/cygwin/2001-07/msg01696.html

* unpack the sources with Cygwin tar (the extra CR's that caused the
  build to fail are added by programs such as WinZip)

then build it according to the instructions
	http://gcc.gnu.org/install/index.html

I don't have any other problems building the GCC 3.0 release for C/C++.

By the way, the plateform-specific installation notes says
> Current (as of early 2001) snapshots of GCC will build under Cygwin 
> without modification.
that seems to imply that 2.95.x might not work.
