GCC question

I have some code which was originally SGI native, then moved to Linux 
(FC14 x86_64 & CentOS 5). I am now interested in getting it going under 
FreeBSD 9.3R. Due to differences in system header file includes, I need 
to tweek some of my app-specific header files. I have poked around the 
(*COPIOUS* !!!!) GCC man page & I couldn't find (or missed) either how 
to get it to regurgitate its default compiler-defines or a tabulation of 
those defines, so I can use them to conditionally include system headers 
in my own header files. Where is this info :-) ? TIA & have a nice 
(long) weekend.
