dnl we need to have an environment variable set when building on OS X.
dnl i'm not sure of the right way to do that. writing 'export ...' to
dnl the makefiles isn't portable. here we'll hijack XXXDEPMODE (where
dnl XXX depends on the language) to insert setting the environment
dnl variable when running the compiler. we'd like to put that in CC,
dnl CXX and OBJC but that breaks depcomp. let's hope this works.
