Keep gcc-libs as a compatibility package that depends on the new cc-libs metapackage and libgomp. The previous split (msys2#28751) moved the omp provision from gcc-libs to libgomp without retaining a dependency edge between them. During a system upgrade, the old gcc-libs package had to be removed because the split runtime packages took ownership of its files. This also removed the only installed omp provider. Although libgomp provides omp, pacman only searches for providers while resolving forward dependencies of packages already selected for the transaction. The missing omp dependency was detected later, during the final reverse-dependency validation. That validation reports broken dependencies but does not add new provider packages to the transaction, so libgomp was never selected automatically. Add a concrete cc-libs package for the common GCC runtime libraries and turn gcc-libs into a compatibility package depending on matching versions of cc-libs and libgomp. Upgrading the installed gcc-libs package now pulls libgomp into the transaction before reverse-dependency validation, preserving all existing omp dependencies. Keeping libgomp outside cc-libs also allows new common-runtime consumers to avoid installing the OpenMP runtime when it is not required. Move the tzdata dependency to libstdc++, which is the component using the C++ time-zone database.
