* adaint.c
(__gnat_file_exists): Do not use __gnat_stat for RTX.
(__main for RTX in RTSS mode): Create this dummy procedure symbol to
avoid the use of this symbol from libgcc.a in RTX kernel mode.
* cio.c
(put_int, put_int_stderr, put_char, put_char_stderr): For RTX we call
the function RtPrintf for console output.
* argv.c Do not use the environ variable for RTX.
* gnatlink.adb (gnatlink): The part that handles the --RTS option has
been moved before the call to Osint.Add_Default_Search_Dirs in order
to take into account the flags in system.ads (RTX_RTSS_Kernel_Module)
from the appropriate run time.
* targparm.ads
(RTX_RTSS_Kernel_Module_On_Target): Add this flag that is set to True if
target is a RTSS module for RTX.
* targparm.adb (Targparm_Tags, RTX_Str, Targparm_Str): Add tag RTX for
RTX_RTSS_Kernel_Module
(Get_Target_Parameters): Add processing of RTX_RTSS_Kernel_Module flag.
* gcc-interface/Makefile.in (LIBGNAT_TARGET_PAIRS for RTX): Use gcc
exception handling mechanism for Windows and RTX in Win32 mode, but
not for RTX in kernel mode (RTSS).
(LIBGNAT_SRCS): Remove ada.h
