You should ask that question in the GCC mailing list. The standard has nothing
to do with how long compilers take to compile anything. The standard doesn't
care if the algorithms rerquired to implement it are quadratic or cubic or
exponential.

Suggestion: since this is clearly a generated file, instead of using
std::unordered_set, use the gperf application or another perfect hash
generator.
