Proposal: Remove or reduce math-finite.h

[Wilco Dijkstra]

Hi,

Note that removing math-finite.h has no effect inside GLIBC itself -
internal math calls use wrappers which continue to be used.

Only external C/C++ code would be affected. Since all commonly
used functions already have their wrappers removed, this won't have
any effect on performance. Any other functions deemed performance
critical can have their wrappers merged on an as needed basis.

So I don't see any point going for something half-way which only
increases complexity further. Removing it (and all other odd math
inlines) is the right way forward - and long overdue.
