1 This subsystem ensures that we can always use a certain core set of
2 functions and types, that are either provided by the OS or by replacement
3 functions / definitions in this subsystem. The aim is to try to stick
4 to POSIX functions in here as much as possible. Convenience functions
5 that are available on no platform at all belong in other subsystems
8 The following functions are guaranteed:
46 mkstemp (a secure one!)
50 readline (the library)
113 mktemp (for mkstemp and mkdtemp)
