Hello,

I'm not sure if this is the right list for this, but I had some trouble
building a PowerPC + Intel binary of ruby 1.8.4 on Mac OS X.
Specifically, a define was missing, and the CC I set wasn't used to
build extensions.  It took a couple of changes to configure for me to
fix it (patch below).

How to port these changes back from configure, to the sources that
generate configure, I don't know, sorry.  But, my hope is that someone
here is much more familiar with the generation of configure, and can
port these changes back for inclusion in the next Ruby version.

For the curious, the necessary configure line for me, on OS X 10.4.4
with Xcode 2.2, was: CC="cc -isysroot /Developer/SDKs/MacOSX10.4u.sdk"
LD="ld -syslibroot /Developer/SDKs/MacOSX10.4u.sdk" ./configure
--enable-fat-binary="ppc,i386"

thanks,
