asm vs __asm__

When GMP uses gcc style inline assembler in C files, like in
gmp-impl.h, "__asm__" is used in most places, but some use just "asm".
One reason for using __asm__ is that it makes it possible to compile
the code with gcc -std=c89 (which is useful for finding accidental
uses of Gnu C or c99 features). I don't know if there are any
drawbacks to "__asm__".
