Make gnu99 the default for gcc 3.3.6 and 4.2.1, not gnu89. While these versions of gcc don't have full C99 support, it is better than defaulting to C89 when building modern software. OK deraadt@

add support for -msave-args in gcc on amd64 i got sick of not having arguments in ddb stack traces on amd64, which is because amd64 passes arguments in registers, and it's impossible to figure out where they go without dwarf info, and when you have dwarf info it is complicated. solaris has a simple solution for this. they tweaked their compilers to accept an -msave-args option which makes functions store their arguments on the stack, while maintaining compatability with the System V AMD64 ABI. tools (eg, ddb) can then look at the stack to get access to function arguments in traces. this ports their changes to gcc 3 to our gcc. ok deraadt@

Introduce a new compiler warning, -Wstack-larger-than-N, to report functions which are too greedy in stack variables. This is intended to be used for kernel compiles, where this warning will be enabled for a reasonable size (after a few weeks grace period so that people can upgrade their compiler). Please note that this warning relies upon md code, and as such is only available on platforms OpenBSD runs on; also, the stack size being warned on is only the local variables size, regardless of the ABI stack usage requirements and the callee-saved registers; which means a function may be warning-clean yet need more stack space than meets the eye; the actual size being checked on may change to include these extras in the future.
