Does one that currently doesn't have a Squeak port count ?

"available" and "useful" have varying degrees of truthness.

IMHO - Only if the assorted information on porting Squeak
	 to other platforms includes some instructions on
	 what to do if gcc isn't available on that platform.

Just for curiosity's sake & FWIW - Your test program doesn't 
compile with: 

	Compaq C V6.4-008 on OpenVMS Alpha V7.3    
	(It's ANSI compliant)

No surprise.... probably the whole "GNU C goto" thing
you mentioned. So it actually running isn't an issue.

but that could just be my ignorance in setting the appropriate 
compiler flags (Though I did try the "Do things the GNU C way"
flag it had no positive results.) since I rarely go near C.
