The native Gcc compilers have been updated to the latest upstream
snapshot version of the gcc-13 branch:
gcc-14.2.1+20241102
This build incorporates the experimental v4 patch from T. Yano to use
the newlib locale function in libstdc++ so that other locales (aside
from "C") become usable.
Cygwin does not allow multiple versions of the compilers to be installed
concurrently.
For this build, the D compiler has been disabled since it does not
bootstrap due to the missing Phobos runtime on Cygwin. No testing
beyond the compiler testsuite has been done. Libgccjit is now building
and part of the release again.
I realised there are docs provided only for gcc/g++, objc/objc++,
gccint, gfortran, libgccjit, libgomp, libquadmath, but nothing for
libstdc++, not even info or man pages.
Is there any chance we could possibly get libstdc++.info* or man pages
included with the build, or as (a) separate -doc package(s), and
possibly other libraries or components where info or man pages are
available, and may not currently be built or installed?
I struggled to find any Cygwin or online docs mentioning libstdc++,
until a poster linked:
https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html,
One upstream refuses to support distros that do not support C++20
compilers!
Given that cygwin/-devel is built with the old ABI, is there any point
in trying to build libraries/packages that *require* the new ABI
features in C++20?
I am asking to adopt dependent orphaned packages, just so I *can*
rebuild them with the new ABI, so is trying this exercise going to be
futile?
Mintty fails to build with gcc-14 and gcc-15. There are some peculiar
settings of #define WINVER which mintty does for a purpose; however,
this was not a problem until gcc-13.
