Charm++ parallel programming system

Hi!

It's rather hard to pass quoted options to charmc. For example, the following command fails when source code uses NAME macro as a c-string:

$ charmc -DNAME=\"foo\" ...

It is caused by “eval” inside charmc script which consumes quotes by itself. The latter example succeeds when both ce9bbf8f52ffdafd0a6b040f4b27039bfb496e79 and 1d6d611a9e6fc7d8dbb41bdf797d91480c21f850 are unrolled.

I don't know how to fix this easily. However mpicc script is to perform the same task (it has to pass some user's option to compiler/linker). As I can see mpicc from my distro tries to quote options in some cases though it may be fooled quite easily.

    case $arg in

    ...

    # Unrecognized args.  Because we do an eval, we need to
    # carefully quote any args that contain quotes.
        *\"*) 
    qarg="'"$arg"'"
    allargs="$allargs $qarg"
    ...    
    ;;
        *\'*) 
    qarg='\"'"$arg"'\"'
    allargs="$allargs $qarg"

    ...
 
    esac

Maybe something like this should be done in charmc script...
