ImportC: unneeded macros are translated to enums

[drpriver]

trafficstars

If you use ImportC to generate a .di file, you get a huge number of implementation macros that start with two underscores. Identifiers starting with two underscores are reserved by the C standard for use by the implementation and it is undefined behavior for you to define one in your program etc. For that reason, no API that anyone wants to use will expose anything with two leading underscores.

For example of how this output is excessive, using ldmd2 to generate a .di file from an empty .c file outputs:

// D import file generated from 'a.c'
extern (C)
