???.  It works just fine with

[descartes:~/programs/gambc40b13] lucier% /pkgs/gcc-4.0.0/bin/gcc -v
Using built-in specs.
Target: powerpc-apple-darwin8.1.0
Configured with: ../configure --prefix=/pkgs/gcc-4.0.0 --with-gmp=/ 
pkgs/gmp-4.1.3 --with-mpfr=/pkgs/gmp-4.1.3
Thread model: posix
gcc version 4.0.0

So why you say it's not a regression, I don't know.

And 4.0.0 is now the *only* version of gcc that will compile Gambit-C  
correctly;

[descartes:~/programs/gambc40b13] lucier% /pkgs/gcc-4.0.0-apple/bin/ 
gcc -v
Using built-in specs.
Target: powerpc-apple-darwin8.1.0
Configured with: ../configure --prefix=/pkgs/gcc-4.0.0-apple --with- 
gmp=/pkgs/gmp-4.1.4 --with-mpfr=/pkgs/gmp-4.1.4 --enable-languages=c,c 
++,f95
Thread model: posix
gcc version 4.0.0 (Apple Computer, Inc. build 5018)

gives me the same error; the Xcode 2.0 gcc compiler was a POS; and with

[descartes:~/programs/gambc40b13] lucier% /usr/bin/gcc -v
Using built-in specs.
Target: powerpc-apple-darwin8
Configured with: /private/var/tmp/gcc/gcc-5026.obj~19/src/configure -- 
disable-checking --prefix=/usr --mandir=/share/man --enable- 
languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg][^+.-]*$/ 
s/$/-4.0/ --with-gxx-include-dir=/include/gcc/darwin/4.0/c++ -- 
build=powerpc-apple-darwin8 --host=powerpc-apple-darwin8 -- 
target=powerpc-apple-darwin8
Thread model: posix
gcc version 4.0.0 (Apple Computer, Inc. build 5026)

I get

[descartes:~/programs/gambc40b13] lucier% gsi
Illegal instruction

The last two are not the FSF gcc team's problem, of course, but why  
go from a compiler that works on PowerPC darwin to one that doesn't I  
don't know.
