Hi Paco,

I agree, but I found no simple way to change mkgmap.
I assume that you consider a non empty stderr file as
an error, so maybe we can check whether anything was
written to stderr, but sometimes we use this file also for
important hints like this:
"WARNING: input files have different code pages"

BTW: Also splitter doesn't make sure that it ends
with a non-zero return code in case of errors, but
it tries to do so.
