 `We now have the C sources of virtex, as produced by web2c. We can get a
 `working virtex out of it, we can let it dump a core and we can
 `produce a somewhat working TeX from it with undump. 
 `
 `But, this TeX ignores all environment variables. A short
 `examination shows, that the procedure, which reads the
 `environment is never executed by the undumped program. This may
 `be a fault (feature) of undump, but I believe that surely
 `somebody has fixed it, since the environment variables are
 `essentials. Furthermore, it seems to work with the Pascal derived TeX.

There is a bug in the distributed version of ctex.ch. I believe it has been
fixed in newer version. Anyway here is a patch:
