Here are some miscellaneous tips for good code styling:
Proper Linux Kernel Coding Style

Personally, I tend to have symbols #defined to a constant 0 or 1 depending on whether or not a function is enabled, and then just use if(SYMBOL) as a guard and let the compiler's dead code eliminator take it out for me at compile time (because if(0) {blah;} shouldn't put any code in the resulting .o file with any optimizer worth its salt. Borland C for DOS managed simple dead code elimination 20 years ago...)
