 Try
 
 gcc <options> file.c -E -H > /dev/null
 
 which just lists the header trail.  Then have a look at the first header
 where they diverge, and figure out why.  It's either because your path
 is different, or a command line or builtin macro is different.  I can't
 help you any more than that I'm afraid.
