Please check new TBOOLEAN definition on all platforms.

[Hans-Bernhard B. <br...@ph...>]

Hello, everyone,

as Ethan just found out, the new way TBOOLEAN is defined I checked in on
Tuesday exposed some lurking bugs.  I've now added the relevant #define's
for HAVE_STDBOOL_H and HAVE__BOOL to all the preset config.h files.  I've 
assumed that both of these conditions are true, on all those platforms.

So, please, everyone who's building gnuplot on one of the relevant
platforms (cygwin, MinGW, Amiga, OS/2 and MSVC++), check that this is
indeed the case.  With both defaulting to true, you'll get solid compiler
errors if you have to toggle them.

We may have to prepare another (hopefully the last!)  release candidate
tarball because of the possible consequences of this change.  Sorry about
that, but this seemed the only reasonable way we would ever get out of
that mess with MacOS X.
