Problem building htp lib on OSX 10.5 related to pedantic-errors not ignoring system headers in gcc < 4.1

Making all in htp

gcc version 4.0.1 (Apple Inc. build 5493)

Problem seems to be that gcc version 4.0.1 has a broken implementation of -pedantic-errors that doesn't ignore System headers

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25171

Solution for gcc was to fix gcc, I don't see a good workaround other than disable pedantic-errors on OSX 10.5 :(
