The eval call in these scripts was failing for me because the path to
them on my windows machine contained spaces. I also fixed some
copy/paste-os from when (evidently) the mc.sh script was created by
copying the rc.sh script and modifying it.

* mh/to_erl-error-messages:
to_erl: Include strerror(errno) in error messages
OTP-8325 to_erl will now include the system error string in error messages
to make it easier to understand what the real problem is. (Thanks
to Magnus Henoch.)

to_erl likes to print the message "No running Erlang on pipe ...",
no matter what the problem actually was. The wording might make
you forget that you just need to run to_erl as another user,
for example.
With this change, to_erl will print the system error message
in addition to its own.
Example output:
No running Erlang on pipe pipes/erlang.pipe.5: Permission denied
(wrong user, wrong permissions, etc)
No running Erlang on pipe pipes/erlang.pipe.5: No such device or address
(this actually means "no running Erlang")
No running Erlang on pipe pipes/erlang.pipe: No such file or directory
(not only is there no running Erlang, there are also no pipes at all)

The wx application will only work in the SMP emulator,
so the -wx option for 'dialyzer' must force the -smp
option when starting the emulator.
Make sure that -wx in *any* position on the command
line (not only as the first argument) forces the
SMP emulator.
