MSVC and newer GCCs support:

#pragma message ( "your warning text here" )

In GCC the other syntax is also commonly used:

#warning "you warning text here"

IIRC gcc warns that `#warning` is a gcc extension. So you'll get two warnings instead of one. – bitmask Aug 05 '12 at 19:13
@bitmask The gcc documentation says that the warning can be disabled: `-Wno-cpp` – quamrana Aug 05 '12 at 19:47
