_EWL_FORCE_ENABLE_BOOL_SUPPORT

This tri-state flag has the following properties:

• If not defined, then the C++ library and headers will react to the settings in the language preferences panel (as in the past).
• If the flag is set to zero, then the C++ lib/header will force " Enable bool support" to be off while processing the header (and then reset at the end of the header).
• If the flag is set to one, then the C++ library and header will force " Enable bool support" to be on while processing the header (and then reset at the end of the header).

If _EWL_FORCE_ENABLE_BOOL_SUPPORT is defined, the C++ library will internally ignore the " Enable bool support" setting in the application's language preference panel, despite the fact that most of the C++ library is compiled into the application (since it is in headers) instead of into the binary C++ library.

The purpose of this flag is (when defined) to avoid having to recompile the C++ library when " Enable bool" support is changed in the language preferences panel.

With _EWL_FORCE_ENABLE_BOOL_SUPPORT defined to one, std::methods will continue to have a real bool in their signature, even when bool support is turned off in the application. But the user won't be able to form a bool (or a true/false). The user won't be able to:

bool b = std::ios_base::sync_with_stdio(false);

// error: undefined bool and false

but this will work:

unsigned char b = std::ios_base::sync_with_stdio(0);

And the C++ lib will link instead of getting the ctype link error.

Changing this flag will require a recompile of the C++ library.
