So far the lib function __getreent always returned _impure_ptr. On Cygwin this is only correct after _impure_ptr got initialized. The inline function in include/cygwin/config.h always returns the right _reent ptr, though. After introducing per-thread locales, the __getreent function is called prior to initialization of _impure_ptr (from dll_crt0_0) to access the locale pointer, which leads to a crash. Fix the __getreent lib function for Cygwin to return the correct _reent pointer all the time. Rename inline function to __inline_getreent and introduce a macro __getreent calling the inline function. Change the lib function __getreent to call __inline_getreent on Cygwin. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
