-------------------------------------------------------------
A little while ago (January 91) I posted the complete source files
for xxgdb version 1.01.
Please find in the following the differences from version
1.01 to 1.03.
Please post this complete message to comp.sources.x

Add source files selection in file button.
Special test for core file in file button.
Fix bug includeDir resource.
Fix bug source file directories.
Add patches for SUN-OS3.
Add strstr function in gdb_parser.c (with #ifdef NEED_STRSTR)
Remove bad test for MIPS and BSD in case of GDB.
Miscellaneous patches for lint.
Port to SYSV + SCO +SYSV32.
Fix bug up/down/frame when arguments are on several lines.
Fix bug in UpdateMessageWindow when arguments are too long.
Fix bug define commands in .gdbinit or source files
Add db_name and db_prompt option (GWC)
and miscellaneous bugs.
TO PATCH XXGDB FROM VERSION 1.01 TO VERSION 1.03 :

See the XDBX_README file for more information on XDBX.
! XXGDB has been originally tested on SUN 4 running OS 4.1.
! It should also run on SUN OS3.
+ Also, any System V should be able to build by setting the -DSYSV flag.
+ SCO Unix also requires the -Dsco flag. Bull DPX/2 [23]00 requires the
+ -Dncl_mr flag as well as -DSYSV. Some systems may also need to set
+ -DUSG to use the GNU malloc instead of the native one. The GNU malloc
+ works much quicker and is much more reliable. SCO Unix requires GNU
+ malloc to work correctly. GNU malloc is not provided here, you should
+ get malloc.c and getpagesize.h from the source of gdb.
+
+ Also note that if building on SCO you must also link with -lsocket
+ and if building on DPX/2 you must also link with -linet. You will need
+ the R4 release of X11 for both.

! character.
!
! - For systems which do not have the ANSI strstr function in their
! library, one is included in gdb_parser.c and is compiled if NEED_STRSTR
! is defined.
!
! - if you define UNDISPWIN when compiling, then the display window
! will disappear when there is nothing to display.
! (eg, add -DUNDISPWIN in DEFGDB definition in Imakefile).
! See display_info_handler function in gdb_handler.c
!
! - The name of the debugger called by xxgdb is by default 'gdb'.
! It can be overridden with the environment variable XXGDB_DEBUGGER.
!
! - DO NOT modify the gdb prompt (using the 'set prompt' command).
! XXGDB assumes that the gdb prompt is 'gdb' or the XXGDB_DEBUGGER
! environment variable if defined.
!
! There are two new application resources and command line args:
! - db_name can be used to specify the name of the debugger to
! override the default "gdb" (instead of using an env. variable).
! - db_prompt can be used to specify to xgdb the string to be used by
! the debugger as a prompt. The default is to expect the prompt
! used by the debugger to be the name of the debugger enclosed in
! parenthesis. This is no good for gdbvx, which expects a prompt
! of (gdb).
