// Build-time assertion.
// -------------------------------------------------------------------------------------------------

/*
    Build-time assertion can do compile-time checking of data structure sizes, etc. This works by
    declaring a negative-length array if the conditional expression evaluates to false.  In that
    case, the compiler issues a syntax error and stops the compilation. If the expression is
    true, we get an extraneous static single character array in the scope of the macro.

    Usage:

        KMP_BUILD_ASSERT( sizeof( some_t ) <= 32 );
        KMP_BUILD_ASSERT( offsetof( some_t, field ) % 8 == 0 );

    Do not use _KMP_BUILD_ASSERT and __KMP_BUILD_ASSERT directly, it is working guts.
