-# Determine whether the compiler is or may be producing universal binaries.
-#
-# On Mac OS X 10.5 and later systems, the user can create libraries and
-# executables that work on multiple system types--known as "fat" or
-# "universal" binaries--by specifying multiple '-arch' options to the
-# compiler but only a single '-arch' option to the preprocessor. Like
-# this:
-#
-# ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-# CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-# CPP="gcc -E" CXXCPP="g++ -E"
-#
-# Detect this situation and set APPLE_UNIVERSAL_BUILD accordingly.
