/* OK, now define a decent interface to ctype macros. The regular

ones misfire when you feed them chars >= 127, as they understand

them as "negative", which results in out-of-bound access at

table-lookup, yielding random results. This is, of course, totally

bogus. One way to "solve" this is to use `unsigned char'
|
|
everywhere, but it is nearly impossible to do that cleanly, because
|
|
all of the library functions and system calls accept `char'.
|

Thus we define our wrapper macros which simply cast the argument to

unsigned char before passing it to the <ctype.h> macro. These

versions are used consistently across the code. */
