/**
 * see rationale in wposix.h.
 * we need to have CRT functions (e.g. _open) declared correctly
 * but must prevent POSIX functions (e.g. open) from being declared -
 * they would conflict with our wrapper function.
 *
 * since the headers only declare POSIX stuff \#if !__STDC__, a solution
 * would be to set this flag temporarily. note that MSDN says that
 * such predefined macros cannot be redefined nor may they change during
 * compilation, but this works and seems to be a fairly common practice.
