Package: mingw32-runtime
Version: 3.13-1
Severity: normal
Tags: patch
The definition of _TSCHAR, _TUCHAR, _TXCHAR, _TINT are missing in
tchar.h. The types are normal present in tchar.h shipped by Microsoft
and other vendors, so the lack of them makes impossible to use MinGW
to compile the source code that rely on these types.
The lack of _TUCHAR is the most unfortunate, because the cast to _TUCHAR
is often necessary to guarantee that in non-UNICODE case, the argument
of character classification routines is inside of the allowed range.
For example:
_TCHAR *ptr;
if (isdigit((_TUCHAR)*ptr))
do_something();
If the cast to _TUCHAR were omitted then in non-UNICODE case (i.e. when
TCHAR is char) the argument of isdigit may become negative, which is not
allowed by the C standard.
I have attached the patch that correct this problem. In this patch, I
also moved the definition of _TCHAR inside __TCHAR_DEFINED ifdef block.
(If the _TCHAR_DEFINED macro is defined, it means that TCHAR type is
defined, while __TCHAR_DEFINED means the same for _TCHAR).
