Cannot reproduce this bug in GDB version 14.2. Tested both the GDB command line
and GDB/MI KDevelop integration. The original (slightly updated) KDevelop test
function GdbTest::testBreakOnReadBreakpoint(), which used to fail and which
Niko Sams disabled in 2009 because of this bug, passes now without the error
message "Target does not support this type of hardware watchpoint.".

Therefore I recommend resolving this bug.

I also tried, with gdb head, and this seems to work.
I'm going to close this now, please comment and/or reopen
if it's still an issue for you.

This is a consequence of moving watchpoint ops to the target vector, and
to the fact that the native target is only pushed when the inferior is created.

The workaround is running to main before setting the read or access
watchpoints.  E.g. with, '(gdb) start'.

Plain "watch" works, because gdb creates a "software watchpoint" then,
and upgrades it to a hardware watchpoint later, when the process is
actually created (and the native target is pushed on the target stack).
