Multicompiler support for Inline Asm (x86)

For inline asm code I use __asm for vc++ compiler and __asm__() or asm() construct for gcc under linux. (intel/at&t syntax accordingly)

Is there a way to declare inline assembly (x86) in C for them both in a universal way?

P.S. An automated tool for incorporating both is also acceptable.

As an alternative...

I presume you use Visual C because it's a Windows platform?

Why not use gcc for both Windows and Linux platforms?

Then it's the same source and same assembly format !

Put the assembly in a macro and use the pre-processor to make the correct code.

#ifdef GCC
#define MY_ASM_CODE __asm() { blah blah blah}
#endif

#ifdef MSVC
#define MY_ASM_CODE __asm { blah blah blah }
#endif

int main(void)
{
  MY_ASM_CODE;
  return 0;
}
