GUN 'as' may take intel-style code, but I'm pretty sure that the compiler (GCC) 
will only accept the AT&T style.  The back end of the compiler needs to know the 
input/output registers, and if that information is not explicitly given in the 
extended-asm syntax, then the compiler must parse the ASM and extract the 
information by itself.  This is what VC does, but I think GCC probably doesn't 
have support for this.

If you're considering keeping separate libraries for the ASM code then I think 
breaking the code out into .asm files and assembling it with NASM/YASM is the 
right way to go.
