AX_CXX_VERBOSE_TERMINATE_HANDLER
@end smallexample

@majorheading Description

Check if the terminate handler for the current compiler/standard library
prints useful information to stdout/stderr (i.e. the type of the
uncaught exception and/or the what() string).

The intended use case for this check is to help program authors decide
if they need to add a top-level try-catch or custom terminate handler to
print useful information if an uncaught exception occurs, or if this
task can be left to the standard library implementation. Alternatively,
it can be used to detect if such output needs to be silenced with a
custom terminate handler.

Output:

Define HAVE_VERBOSE_TERMINATE_HANDLER if useful information is printed.
