=begin
I upgraded to Xcode 4.3 which has clang 3.1:

Apple clang version 3.1 (tags/Apple/clang-318.0.45) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin11.3.0
Thread model: posix

After running ((%autoconf; CC=clang ./configure; make%)) clang complains about -ggdb:

clang: warning: argument unused during compilation: '-ggdb'

Also, the clang manual page notes for -g -O0 will generate the best information:

   -g  Generate debug information.  Note that Clang debug information
       works best at -O0.  At higher optimization levels, only line number
       information is currently available.
