Essentially you say that for *all* packages I should set `--prefix' to
a non-msys-mounted directory, right?

OK, tried that for bison.  Executing it within the msys shell, it
finds m4sugar.m4.  However, I still get

  m4 subprocess failed: No such file or directory 

So I tried to install m4 also into my new prefix.  And bison still
doesn't work, aborting with the same error!  This is extremely
frustrating.

Note that I actually need `bison' only to be run within msys, as an
update to version 2.4.2, which is too old for my purposes.  For this
special situation, I would thus like to build an `msys-bison' program
in `/usr/local'.  How can I build that?
