[Efi332] Standard GNU C library for CYGWIN

[David Eicher]

Hi Doug,

Appreciate this. But..., I don't see an attachment. Did you embed the code
in the email? I'm not finding it.

Thanks,

Dave

Here's my current codebase. The ISR is located in interrupt.s, which 
contains the exception service routine for all my interrupts, and the 
actual communications functions are in comm.c.
