I'm looking for a Bourne shell script compiler - that is, a compiler that
accepts a Bourne shell (sh) script as input and produces C code as output.
I have a vague recollection that such things exist, but can someone point
me to them? I'm working with Sun equipment, though I'm open to stuff that
hasn't been ported to Sun but that DOES have source code that I could use
to do my own port. PD is preferable to commercial products.

Based on some experience with a pre-Bourne (!) shell compiler, long ago, the benefits of such a thing are limited unless it incorporates extensive knowledge of the more common programs invoked from shell scripts. Running a shell script comprises parsing, interpretation (variables etc.), and execution (fork/exec) of programs. A simpleminded shell compiler eliminates the parsing and streamlines much of the interpretation, but it's the execution that is usually the bottleneck. You won't see a big win unless the compiler is smart enough to optimize out some of the execution. -- Henry Spencer @ U of Toronto Zoology, henry@zoo.toronto.edu utzoo!henry -- Send compilers articles to compilers@iecc.cambridge.ma.us or {ima | spdcc | world}!iecc!compilers.
