Commit Message
Say we do:
...
$ make check RUNTESTFLAGS="gdb.dap/ada-nested.exp gdb.dap/pause.exp"
...
and add a perror at the end of pause.exp:
...
dap_shutdown
+
+perror "foo"
...
We run into:
...
UNRESOLVED: gdb.dap/ada-nested.exp: compilation prog.adb
...
This happens because the perror increases the errcnt, which is not reset at
the end of the test-case, and consequently the first pass in the following
test-case is changed into an unresolved.
Version 1.6.3 of dejagnu contains a fix which produces an unresolved at the
end of the test-case, which does reset the errcnt, but this is with version
1.6.1.
Furthermore, we reset the errcnt in clean_restart, but the pass is produced
before, so that doesn't help either.
Fix this by resetting errcnt and warncnt in default_gdb_init.
Tested on x86_64-linux.

Seems reasonable to me, thanks.
