As several people pointed, texx2 doesn't compile with a normal C compiler.
I used `gcc', which lets you initialize automatic aggregates -- it seems
this isn't a common addition (*sigh*).

Many of the changes are straight-forward (moving the automatics to the
global level), but many aren't (for those, XtSetArg needs to be used).

Also, you can't compile it with gcc 1.33 because gcc 1.33 is buggy & dies.
I used gcc 1.31.

There's another problem, which is related to a mising * in  ``mio.h''.
A correct version follows:


---mio.h---
/*

/*
 * Memory I/O: numbers.
