Fix two remaining problems for C99/C23 compatibility.
With this, package builds with GCC-15.
true and false are strings, so replacement is trivial
and doesn't interact with ABI.
Casts to Widget are uses everywhere in this program, and
are correct, as MatrixWidget embeds same core struct from Xt
as Widget consists of, as first member.
XtRImmediate indicates that next pointer would be interpreted
as a value, so integer reinterpreted as a pointer to low mem is
actually fine, it won't be dereferenced and won't crash whole
program.
