Nevertheless many existing toolchains throw warning messages, and I see no reason to drop support of these older compilers.
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

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 '//'.
