Why?  The number one question I get from developers new FreeBSD is 'I wanted to use libfoo from ports, I stalled it, and now [gcc,clang] doesn't find the headers, why not?'  No one has yet provided me with a sane reason why our system compiler would not look in the standard locations where we install headers and libraries.  Running configure scripts on FreeBSD is a colossal pain because of this - you often need to explicitly say -with-foo-include=/usr/local/include -with-foo-lib=/usr/local/lib for an arbitrary number of values of foo, depending on the library.

Please, please, please, can we put our standard library and header paths in the compiler standard header or library paths, or can someone give me a good reason other than 'it's a stupid idea' why we should force every single program that anyone compiles on FreeBSD to do CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib?
