Done. f2c

If this is done automatically, it is to fit existing C code into a C++
framework quickly.

Compiling C->jvm is reasonable, particularly if it's debugged and to
be linked with new JAVA code.

I think the original request is reasonable. In fact, IDL to C
directly would be something of a pain, but via LISP it would not be as
hard as you'd think. IDL4 is a lot like a crippled lisp with FORTRAN
syntax. For IDL4, and IDL->LISP compiler would be quite feasible, if
appropriate widget and math libraries were added. Lisp is easily
compiled to C or assembly.

For IDL5 this is more difficult, because of the pointers. If those
are avoided, IDL->Lisp may still be feasible.
