/* chartostring.c: change a character (i.e., an integer) to a
one-character string.
Written in 1994 by Karl Berry. Public domain. */

/* This is needed because web2c turns the Pascal construct 'x' into the
C character constant 'x', not the string "x". And we need to keep it
that way because that's how xord is initialized, etc. But sometimes
we want one-character strings -- e.g., in tangle.ch and weave.ch.
There's no real alternative to wasting the two bytes of memory (plus
malloc overhead) here, but it doesn't matter. */
