Description
legacy support uses defines such as:
#if __MP_LEGACY_SUPPORT_UTIMENSAT__
It is not legal to define identifiers beginning with double underscore, and defining identifiers beginning with a single underscore seems bad too.

- All identifiers that begin with an underscore and either an uppercase letter or another underscore are always reserved for any use.
- All identifiers that begin with an underscore are always reserved for use as identifiers with file scope in both the ordinary and tag name spaces.

We also went out of our way to make them long winded names such that I really doubt there is ever going to be a clash..

I have no plans to change these at this point.

The reason these identifiers are reserved is so the standard library can use them without fear of introducing name collisions in programs. Given how legacysupport works, it is in the same position as the standard library in this respect, and could be considered an (unofficial) part of it.
