- #45430, windows implementation of crypt is not TS
- add Blowfish (using implementation from Solar Designer <solar at openwal dot com>) and extended DES support
- Make crypt features portable:
- if no crypt_r, php's implemetation is used (all algo and TS), php can't be used with unsafe crypt anymore
- if one algo is missing, php's implemetation is used
- Windows always use php's implementation
- removed old code in windows/
sigsetjmp use setjmp. Windows is of course weird in that it seems to
have sigsetjmp but not sigjmp_buf (??) so force it to use setjmp in
config.w32.h.in
Remove config-file-path option from configure under win32; it is not used except to display what might have been chosen, so lets default to the getenv() thingy.
