Sources/WTF/config.h already disables it:
// this breaks compilation of <QFontDatabase>, at least, so turn it off
for now
// Also generates errors on wx on Windows and QNX, because these functions
// are used from wx and QNX headers.
#if !PLATFORM(QT) && !PLATFORM(WX) && !OS(QNX)
#include <wtf/DisallowCType.h>
#endif
I don't think there is a better solution than disabling it for all
modules. Your compile error seems to be the result of not having it
disabled in Sources/WebKit2/config.h. Hope that helps.

Hey all,
I'm currently trying to patch (Qt-)WebKit in order to build it for QNX. Now
I'm running into an issue which I wonder how to address properly. Most *.cpp
files start with the following lines in WebKit:
// file foo.cpp:
#include "config.h"
#include "foo.h"
Now, this might trigger the inclusion of system headers from QNX eventually.
If these contain stuff like e.g.:
// FUNCTION _Tolower
inline int _Tolower(int _Byte, const _Ctypevec *)
{ // perform locale-specific tolower
return (_CSTD tolower(_Byte& 0xff));
}
you get a compile time error:
'tolower_WTF_Please_use_ASCIICType_instead_of_ctype_see_comment_in_ASCIICType_h'
is not a member of 'std'
I see how this is useful for WebKit code, but it should not be triggered for
system includes or third-party includes, should it? Does anyone have an idea
on how I could solve this?
For now I'll work-around this issue by disabling DisallowCType.h on QNX, but I
whether anyone has a better idea.
Cheers
PS: Here's a full error trace that shows how we end up at the function
_Tolower I quoted above:
