This patch does three things:

1/ Uses gethrtime() rather than trying to read the %tick register (the
   latter has issues in MP environments)
2/ Allows Studio to compile in 64-bit and normal optimization.
3/ Removed the need to define lines like "CFLAGS += -Du_int8_t=uint8_t"
   in the snort component Makefile.

It has been sent upstream for consideration by the snort maintainers for
a future release.
