Hi Nicolás,

I was wondering if the recent addition of ucrt support to the mingw64
toolchain could allow the use the math routines from the ucrt (which are
hopefully faster) in place of the current implementations.
Do you know if this would be possible technically and whether there are
any plans in this direction?
Technically, with UCRT one could indeed avoid statically linking our own
implementation of a lot of functions, by calling the CRT version of them
instead; this both would reduce the size of binaries (by statically
linking fewer functions) - this aspect was known to me before. I hadn't
thought about the potential performance benefits of it before though.
I remember that I did try to make a patch to this effect at some point,
but I wasn't satisfied with how it turned out (it felt like it made a
complicated structure into even more of a mess), but I'll try to revisit
it, to see if it'd be worth it still, or if it'd be possible to solve
neater in soem way.
