Dear Autoconf developers,
I would like to reparaphrase my question from last time.
Following the advice from Autoconf manual:
http://www.delorie.com/gnu/docs/autoconf/autoconf_50.html:
The following code in gnuplot breaks compilation on at least two
systems that don't conform to C99 (Sparc

What exactly is the real problem here?
The real problem is that we're testing whether
stdbool.h works in C, and using that test to configure
both C and C++. We should use a C++-specific test to test
whether stdbool.h works in C++.

A serious question: is there any C++ compiler out there which defines
_Bool by default (without including stdbool.h)
I don't know of any offhand (remember, I don't use C++...)
but it seems quite likely that there would be, no? It would
be a valid
Hello,
A sparc solaris user reported a _Bool-related problem to gnuplot tracker.
Long story short: stdbool.h is absent, _Bool is defined in C, but not
in C++. Current header file in gnuplot sources which is used both in C
and C++ goes like
# if ! HAVE__BOOL
# ifdef __cplusplus
typedef bool
