[ptxdist] [PATCH 7/7] cups-filters: new package: additional filters and backends for CUPS

[Roland Hieber <r.hieber@pengutronix.de>]

Upstream is very responsive, merged some patches and made a new release
while I was still packaging the old one :)

+Subject: [PATCH] configure.ac: check for C++11 support
+
+The filters pdftoopvp, bannertopdf and pdftoraster depend on features
+only available in C++11, indirectly also because poppler does not put
+-std=c++11 on its pkg-config CFLAGS (but I'm not sure whether it should
+even do this). Solve this problems by adding -std=c++1 to $(CXX), if
+necessary, or fail if the compiler does not support C++11.

++# ===========================================================================
++#
++# SYNOPSIS
++#
++#   AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
++#
++# DESCRIPTION
++#
++#   Check for baseline language coverage in the compiler for the specified
++#   version of the C++ standard.  If necessary, add switches to CXX and
++#   CXXCPP to enable support.  VERSION may be '11' (for the C++11 standard)
++#   or '14' (for the C++14 standard).
++#
++#   The second argument, if specified, indicates whether you insist on an
++#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
++#   -std=c++11).  If neither is specified, you get whatever works, with
++#   preference for an extended mode.
++#
++#   The third argument, if specified 'mandatory' or if left unspecified,
++#   indicates that baseline support for the specified C++ standard is
++#   required and that the macro should error out if no mode with that
++#   support is found.  If specified 'optional', then configuration proceeds
++#   regardless, after defining HAVE_CXX${VERSION} if and only if a
++#   supporting mode is found.
