My experience is just the other way around:  the following
code throws an error for long long, but gives no warnings for //:

#define CFG_CMD_KGDB            0x00000200ULL   // kgdb    

#if (CFG_CMD_KGDB) 
#define LONG_LONG_WORKS 1
#endif

Compiled with gcc version 2.95.2, and 'gcc -Wall -pedantic'

As this is an excerpt from u-boot, I'm a bit surprised about
your reasoning against '//'.
It might be pretty hard to find a toolchain that compiles
u-boot but throws a warning on '//'.
