Subject: [PATCH 2/4] [DJGPP, Ada] DJGPP support
* ada/ctrl_c.c: Do not use macro SA_RESTART for DJGPP.
* ada/gsocket.h: Do not support sockets for DJGPP.
* ada/init.c (__gnat_install_handler): Implememt for DJGPP
* ada/sysdep.c: Include <io.h> for DJGPP
(_setmode): Define to setmode for DJGPP
(__gnat_set_mode): Add implementation for DJGPP
(__gnat_localtime_tzoff): Use localtime_r for DJGPP
* ada/terminals.c: Add DJGPP to list of unsupported platforms.
* ada/env.c (__gnat_clearenv): use _gnat_unsetenv on all entries for DJGPP
