More correctly -Ae enables "extended ANSI"; -Aa enables strict ANSI.  

I've managed to get things to build with the unbundled compiler using -Ae and
-Aa with various amounts of hackery.  The problem with them is they muck up
the namespace pretty badly and suddenly functions and structures you expect
to find in the include files aren't there anymore and some which you don't
expect suddenly exist (leading to wonderful problems in some GNU code which
at least used to blindly assume it should provide a typedef for uint32_t :(

:-)  The configure code in gdb was broken last I looked (Nov 2001) in repsect
to how it deals with -Aa/-Ae. if I recall the autoconf folks told me they had
fixed those problems.  There's a thread (and a todo on my list) to get this
code fixed.  It just hasn't bubbled back up to the top of my list.
