* stringhelp.c (w32_strerror) [W32]: New.
* w32-pth.c, w32-pth.h: Added real code written by Timo Schulz.
Not finished, though.
* gpgconf-comp.c <ignore-ocsp-service-url>: Fixed typo.
* w32-pth.c, w32-pth.h: New.
* Makefile.am (gpgsm_LDADD): Put libassuan before jnlib because
under W32 we need the w32 pth code from jnlib.
* misc.c (setup_pinentry_env) [W32]: Disabled.
