%description
Complete reviewed GCC source and build rules for a standalone native libstdc++.
The binary subpackage retains the GNU C++ ABI and excludes optional Python GDB
pretty-printers. No compiler or Python tool is installed on the tablet.
%package -n libstdc++
Summary: GNU Standard C++ Library without optional Python GDB helpers
Provides: senemos-native-runtime(libstdc++) = %{version}-%{release}
Requires: glibc >= 2.10.90-7
Recommends: tzdata >= 2017c
%description -n libstdc++
The native GNU Standard C++ Library, rebuilt from the exact Fedora GCC source.
Optional GDB Python printers are outside this target runtime. The source build
checks the original versioned symbol set and executes a native C++ smoke test.
%prep
%setup -q -n gcc-%{version}-%{source_date}
# The inherited patch changes the shared libtool infrastructure used here.
# Remaining Fedora patches affect compilers, other languages or HTML manuals;
# the complete original source RPM is retained as Source99 for provenance.
