// Note that we never export actual 16-bit APIs from these headers, even if
//  we have them marked as OS2API16. This is just for documentation's sake at
//  the moment. If you compile against these headers and link against an
//  OS2API16 function, they will be exist and operate in a linear address
//  space. If you call them from an LX executable, though, the system assumes
//  you're calling in from 16-bit code and exports something that cleans up
//  the details behind the scenes.
// For developing against this API directly on Linux, you should assume this
//  works like OS/2's PowerPC port, and the same 16-bit APIs you used on x86
//  were made 32-bit clean by default for the new platform.
