[AD] zipup.sh again. *sigh* (+cleanup proposal)

[Henrik Stokseth <hstokset@xxxxxxxxxx>]

looks like i was a little bit fast with telling Eric to commit the smart 
dllexport patch. zipup.sh is broken again due to the line that combines all 
the temporary files with exported symbols.

i remember george has earlier said that he thought the run_batch_file() macro 
was kinda ugly. i agree, and i wish to clean up things, so i make the 
following proposal:

all fix scripts are combined into two scripts one for unix and one for dos: 
fix.bat and fix.sh with support for 'cross-fixing'. :o)

then for unix you would run ./fix.sh unix [--quick] and likewise for dos you 
would run fix.bat djgpp [--quick]. and to generate dlls you run 'fix dll'.

so what's the result?
-we only have two fix scripts instead of thirteen.
-zipup.sh will be simpler with no ugly script parsing.
