+Hardware watchpint problems on x86 OSes, including Linux:
+
+1. Delete/disable hardware watchpoints should free hardware debug
+registers.
+2. Watch for different values on a viariable with one hardware debug
+register.
+
+According to Eli Zaretskii <eliz@delorie.com>:
+
+These are not GDB/ia32 issues per se: the above features are all
+implemented in the DJGPP port of GDB and work in v5.0. Every
+x86-based target should be able to lift the relevant parts of
+go32-nat.c and use them almost verbatim. You get debug register
+sharing through reference counts, and the ability to watch large
+regions (up to 16 bytes) using multiple registers. (The required
+infrastructure in high-level GDB application code, mostly in
+breakpoint.c, is also working since v5.0.)

New Features and Fixes
``(gdb) catch signal SIGNAL''

+Overlaps with ``handle SIGNAL'' but the implied behavior is different.
You can attach commands to a catch but not a handle. A handle has a
limited number of hardwired actions.
Replace the code that uses the host FPU with an emulator of the target
FPU.

+
+The "ocd reset" command needs to flush the dcache, which requires breaking
+the abstraction layer between the target independent and target code. One
+way to address this is provide a generic "reset" command and target vector.
