// 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.
