Allow the compiler to notice "constant" header file.
Both gcc and sparse will speed up tokenization by noticing
when a header file is protected by the standard preprocessor
#ifndef .. #endif exclusion.
However, that requires that the headers actually _use_ that
standard exclusion. Some did their own little broken dance.
