Bug ID: 107930
Summary: wchar_t may not be the native character type for
windows
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: unlvsur at live dot com
Target Milestone: ---
Windows APIs have two modes. ANSI 9x and Wide NT. It is still possible the
operating system character type is char, not wchar_t. Plus nobody guarantees
the sizeof(wchar_t) == 2 on windows.
I suggest adding a toggle to set the toggle here on whether A apis or W apis
are called when building with cross-toolchain.
WINVER, _WIN32_WINDOWS and _WIN32_WINNT determine what mode to use. However,
libstdc++ does not provide options to set them.
enum class win32_family
{
ansi_9x,
wide_nt,
#ifdef _WIN32_WINDOWS
native = ansi_9x
#else
native = wide_nt
#endif
};
