CRT getopt() function should use CRT's getenv function instead of WinAPI
GetEnvironmentVariableW because CRT env does not have to be in sync with
WinAPI (e.g. when changing 3rd argument of main() or when changing global
environ variable).
Usage of CRT getenv() is not suitable for UWP builds as in UWP it is
mostly impossible to implement getenv-like function. But CRT has
getenv_s() API which can be implemented by both UWP and mingw-w64.
So use getenv_s() in mingw-w64 getopt() which fixes both issues.
Pali Rohár (4):
crt: Provide mingw-w64 emulation of getenv_s function for all CRT
import libraries
winstorecompat: Provide getenv_s() function
Revert "crt: use GetEnvironmentVariableW in getopt"
crt: getopt: Use getenv_s() instead of getenv()
