On Unix and Linux, the standard libraries and headers are part of the 
platform and they all live in standard places (/usr/include and 
/usr/lib).  Compiler specific file locations are known to the compiler 
(in the case of gcc, these are specified at build time).

Eh?  For the two version I have on this box:
