In an effort to implement the alternative fix of forcing SL to use gcc-4.2
for cc/gcc and g++-4.2 for c++/g++ in the path-prefix-10.6 compiler_wrapper,
I decided to test the fink patch...

Oddly this change to the installed compiler_wrapper doesn't survive through
the bootstrap. If you watch /sw/var/lib/fink/path-prefix-10.6 carefully during
the bootstrap, you will see that immediately after the installation of fink,
the compiler_wrapper installed in /sw/var/lib/fink/path-prefix-10.6, contains
the expected change...
# use Apple gcc-4.2 compilers on SL
case `uname -r` in
10.*)
case $compiler in
cc|gcc)
compiler="gcc-4.2"
;;
c++|g++)
compiler="g++-4.2"
;;
esac
;;
esac
however shortly afterwards in the bootstrap, the compiler_wrapper is replaced
with
one missing this change (from the toplevel compiler_wrapper.in I guess). It is
odd
that we don't see this problem with the path-prefix-clang compiler_wrapper which
also differs from the top-level compiler_wrapper.in.
Any ideas on how to suppress this second installation of the
compiler_wrapper
and why are we doing that in the first place?
