I think architecting a compiler to target the wildly popular GCC, as the 
default configuration, is totally fair.

Sounds like Apple pulled a switcheroo, broke some optimizations by 
introducing bugs, didn't care, and consequently Gambit had to degrade 
gracefully.

Gambit needing a real (not fake) GCC to work best is different from 
vendor saying that they only get their best benchmark performance in 
utterly contrived machine configurations, running at a particular 
temperature during a particular phase of the moon.

BTW, I am a fan of Gambit.  Gambit and Kawa were the main reason that I 
went to such pains to write portable Scheme for so long.  I always keep 
Gambit in my back pocket, in case I ever run into a situation with 
really unusual requirements (e.g., a gazillion threads).  Similar with 
Kawa, in case I ever really-really need to target the JVM.  My strategy 
nowadays is to program for Racket, but know how to port to another 
excellent Scheme descendant if I ever have to.  So far I haven't had to.
