Add an explicit `volatile` qualifier for intrinsic functions that write to TEB; do not rely on the
implicit volatile semantics, just because they have no output.
* If an asm statement reads memory that is not passed with "m", it shall
clobber "memory".
* If an asm statement writes memory that
Source file purecall.c provides emulation of function _set_purecall_handler()
so rename this file to _set_purecall_handler.c. This file does not provide
function named purecall().
Function _set_purecall_handler() is available since msvcr71.dll, so include
source file also into msvcr70.dll import l
Function _copysignf is in i386 natively available only in msvcr120 and
UCRT. mingw-w64 already provides emulation in crtdll and msvcrt i386 import
libraries. Include this emulation also into all other i386 CRT import
libraries.
Note that function _copysignf is available in all x64 and arm versions

Overall, I'm not familiar enough with nontrivial aspects of x86 assembly
to comment reasonably on it - so I guess it's mostly "probably ok, if you
say so".
However this bit caught my eye:
First, these intrins read from and write to thread-local memo

Can you elaborate about the reasoning here? Isn't volatile primarily needed if the assembly has some
side effect that otherwise can't be modelled - e.g. if the outputs of the inline assembly isn't
needed, we still can't skip the whole assembly.
I don't qu
