interprocess/test/mapped_file_test.cpp
Ion Gaztañaga 25bb48435f - Rewritten posix features detection according to the first POSIX/Single Unix Specification that standardized it.
- Added macro for unnamed semaphores as OSX claims this support but returns ENOSYS, which is not very useful.
- Added macro for mapped files, as QNX does not support them.
