[Fedora-packaging] RFD: C/C++ template packages

Hi, Fedora carries some "C/C++" "template"/"header-only" packages (Packages which contain C/C++-headers only). Typically, these packages are being built "BuildArch: noarch". == These packages are supposed to be arch-independent. In reality, many of these packages often are wrapper headers, trying to wrap to something highly OS-/arch-dependent, from system-headers and compiler built-ins defines. I.e. though these packages are supposed to be arch-independent, there is no guarantee nor check whether these packages actually are arch-independent. I am proposing to: Proposal: All "C/C++-template/header-only packages" must be built using an "arch'ed BuildArch", with the resulting binary packages implemented as "Arch: noarch"-subpackages. Benefits: - This would assure such packages would be built on all architectures Fedora supports and not only the architecture noarch-packages are being built. - This would exercise potentially existing configuration-scripts on all architectures and would allow to exercise test-scripts rsp. coding examples (which can be regarded as compilation-checks) on all Fedora supported architectures. Comments, opinions? Ralf
