cygerrno.h. * include/cygwin/config.h (__DYNAMIC_REENT__): Define. * include/cygwin/version.h: Bump API minor version. * cygwin.din: Export __getreent * cygerrno.h: Include errno.h. Fix places where _impure_ptr is used directly to store the errno value. * debug.cc (__set_errno): Ditto. * errno.cc: Remove _RRENT_ONLY define to get errno.cc compiled. * signal.cc: Rename _reent_clib to _REENT throughout. * thread.h (reent_clib): Remove prototype. * thread.cc (reent_clib): Rename reent_clib to __getreent. Return _impure_ptr until MTinterface is initialized. (reent_winsup): Fix a possible SEGV when _r == NULL. Return NULL instead. * MTinterface::fixup_after_fork: Switch reent back to _impure_ptr to keep signal handling running when fork is called from a thread other than the mainthread.
