Not exactly. You will probably end up with something that looks like yacc
output - huge functions and lots of gotos. But still pretty ugly :)

Depends on what purpose you need this C source for. If you want to
recompile and run it as is then the answer is no, forget it. If you
just want to get some general ideas on what's going on, translation to
C might help for one reason - there are tools available for analysing
C sources, eg. building call graphs, xref tables, flow charts etc.


However I wouldn't do that unless absolutely necessary.
