What has changed since GDB-3.5?
(Organized release by release)
+*** Changes in GDB-4.9:
+
+(This is a prototype to remind us of things that should be announced
+in the next release...)
+
+H8/300 simulator
+H8/500 simulator (probably by the next release)
+Z8000 family simulator
+
+Cross-debugging to GO32 targets is supported. It requires a custom
+version of the i386-stub.c module which is integrated with the
+GO32 memory extender. Msg follows:

+Subject: GO32 debugging in devo/gdb
+
+ SUB: GO32 debugging in devo/gdb
+ SUM: <gnu>, gnu->eichin, ian, gnu, gumby, gdb
+
+ My impression is that devo/gdb supports remote debugging of GO32 programs.
+ Is this true?
+
+Yes. I think that even the 4.7 release had everything needed.
+
+ What does a user have to have in the GO32 environment in order to do this?
+ (My guess: our custom-modified GO32. Did we send the changes back to
+ DJ and did they ever get integrated into the standard GO32?)
+
+I asked DJ if he wanted the changes; at the time, he was very busy
+having a daughter. He's back on the net now, I'll give him another
+try. My changes are to GO32 1.07 and the entire source (and an
+executable) are checked in to cvs; the current GO32 is 1.08, I haven't
+tried updating the changes.
+
+ What does a user have to actually do in GO32 in order for this to work?
+ E.g. there seems to be no user-level documentation for this feature.
+
+GO32 includes "go32.exe" and "debug32.exe"; my version is
+"dser32.exe". With a serial link on com1 to the host, use the mode
+command on the target to set the baud rate, then "dser32 a.out" and
+start up gdb (configured -target go32), target remote /dev/ttya.
+Shoudl just work from there.
+
+ I'm wondering if we can announce this as part of what's supported in
+ gdb-4.8.
+
+The hard part is the extender itself -- it needs to be built with a
+native 16-bit compiler (such as Turbo C with Turbo Assembler -- about
+$300 in software, which I do own -- and the assembly code uses enough
+high level features (like structs) that it isn't portable to other
+assemblers.) We have no way to build it with any free tools. I think
+we can ship (or at least make available) the executable for the DOS
+side, I don't think Turbo C has any runtime restrictions.
