On core-updates, p7zip is failing to build with error messages like
../../../../CPP/7zip/Archive/Wim/WimHandler.cpp:308:11: error: use of an
operand of type ‘bool’ in ‘operator++’ is forbidden in C++17
308 | numMethods++;
| ^~~~~~~~~~
This follows from the move to GCC 11 and its use by default of the GNU dialect
of the C++17 standard for interpreting C++ code. (Note p7zip is essentially
abandoned and its code is aging.)
The patch to follow causes GCC to use the GNU dialect of the C++14 standard
instead, as GCC 10 did by default, reducing the error messages to warnings and
allowing the build to complete.
I've tested this on x86-64 and AArch64 and everything seems fine.
