Math functions are special! :)
In error cases, they call a function call _matherr. This function will
typically set only errno. However, programs which link dynamically against
the MSVCRT are permitted to replace the function with whatever they want
(this is documented behavior!); their _matherr might forward it's arguments
to "fire_the_missiles".

[LLVMdev] [RFC] Identifying access to errno
Oh, and I forgot a third "_doserrno" for which no amount of documentation
lends itself to a consistent description of its behavior.
