#
# SYNOPSIS
#
#   AX_CXX_VERBOSE_TERMINATE_HANDLER
#
# 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.
