Default Patches for 64bit linux
I'll be posting patches to improve compatibility with 64bit linux compiles in this thread.

First up, makefile changes to allow it to begin compiling.

This patch merely removes the -march=i686 to allow the compiler to dynamically set arch and in two makefiles it changes the mysql flags from hardcoded to dynamically generated.

If desired, I could create patches so the makefile will selectively add the -march=i686 for 32 bit machines.

Apparently va_lists are not preserved in (most) 64bit linux libraries after vprintf (and variations) calls. This causes segfaults under 64bit when a va_list is reused. This patch avoids reusing va_lists.

I did a whole pile of type casts where MakeAnyLenString was being used with %lu in the format string. This patch is over 400 lines long so rather than post it here, it can be retrieved at:
