BTW, what I found in googling suggested that (1) icc never has defined
__ICC on 64-bit machines, and (2) although it does define __GNUC__ by
default, there is a way to turn that off. So I surmise that your
relevant change was adding a compiler flag that disabled the definition
of __GNUC__. That doesn't seem to have stopped it from accepting
GNU-style asm directives, though, so I kinda wonder what compiler
behavior does change and what was the point of your flag change.

This suggests that configure.in's check for icc is wrong/incomplete:
it only tests if the compiler was previously determined to be gcc,
ie, it defines __GNUC__. Now that we know that can be turned off
in icc, it seems like we'd better check all the time.
