[gambit-list] gcc-4.0 compiler from Apple's Xcode 2.1 seems to work fine

Previously I sent somewhat cryptic instructions on how to build a  
later version of Apple's gcc-4.0.0 that would build Gambit 4.0beta13.

Well, you don't have to do that any more; I suggest you sign up as an  
apple developer and download and install the free Xcode 2.1, which  
installs

[descartes:~/programs/gambc40b13] lucier% gcc -v
Using built-in specs.

Thread model: posix
gcc version 4.0.0 (Apple Computer, Inc. build 5026)

This version of Apple's gcc seems to build gambc40b13 just fine; I  
configured a 64-bit version with

env CC='gcc -mcpu=970 -m64 -force_cpusubtype_ALL' ./configure -- 
enable-single-host

and a 2.7 GHz G5 smokes a 3.6 GHz P4, both running 64-bit code.

Too bad IBM didn't seem to be able to supply Jobs with a low-power  
G5 :-P.
