tset may not compile due to _POSIX_VDISABLE misuse

Dear Thomas,

the latest (5.5-20060909) ncurses does not compile on Mac OS X 10.4.7,
since _POSIX_VDISABLE is defined in <sys/unistd.h> as
#define _POSIX_VDISABLE         ((unsigned char)'\377')
and used in progs/tset.c as follows
#if defined(_POSIX_VDISABLE) && (_POSIX_VDISABLE != -1)
resulting in the following error
../progs/tset.c:689:34: error: missing binary operator before token "char"

I.e. the cast operator (unsigned char) may not work at compile time.

It is a known problem. Please, take a look at

WG15 Defect Report Ref: 9945-1-27
Topic: _POSIX_VDISABLE symbol


cast vs. suffixes

             Sincerely, Michail
