When winegcc is using an underlying POSIX libc (rather than -mno-cygwin) it will only have `char` and `wchar_t` functions. If _TCHAR is neither of these there may be no suitable function to alias _tcs* to.

wine-5.2 (c12089039637dec5e598ed1c41e707f057494242) allowed <tchar.h> to be used without MSVCRT. _TEXT(...) and _TCHAR typedef are useful, but the _tcs* macros may still be unusable.
Omitting them will be a clearer compile error when to not exist than mapping them to e.g. wcs* functions which do not accept a windows WCHAR (!= wchar_t), --- include/tchar.h | 8 ++++++++ 1 file changed, 8 insertions(+)
