I have a SPARCstation that I've just installed Solaris 2.1 on.  I
don't have Sun's C compiler.  I got the Cygnus gcc binaries for
Solaris 2.1 from ftp.uu.net.  Using the Cygnus gcc, how can I compile
the latest version of gcc?  In the Makefile, it has a macro OLDCC;
you're supposed to use cc to compile the the library of arithmetic
subroutines.  If I don't have cc then how can I recompile gcc?

As Jim Lynch (jimlynch@netcom.com) and others suggested, if you do

	make CC=/opt/cygnus/bin/gcc LANGUAGES=c

it properly makes gcc.

When I compile gcc I like to have it recompile itself with itself,
which you can do via "make bootstrap" but that doesn't pass CC on
properly, so in order to get that to work you'll need to edit the
Makefile and for the bootstrap: action, fix the first non-commented
line and add

	CC="$(CC)"

to it.  Now mine says

	$(MAKE) CC="$(CC)" LANGUAGES=c
