In commit 99d09ec45a (VS: Suppress MSBuild default link flags not
specified by project or user, 2025-06-17, v4.1.0-rc1~6^2) we removed our
default `-subsystem:...` link flag from `SHARED` and `MODULE` libraries
in Visual Studio generators for consistency with command-line generators.
However, unlike other flag suppressions for #27004, this change did not
just suppress MSBuild defaults, but actually changed flags the generator
was previously adding itself.
For the linker subsystem flag, consistency across generators should
perhaps achieved by adding the flag in other generators instead of
removing it from Visual Studio generators. Restore the previous
behavior pending further investigation.

cea7f7fc32 Linux: Do not force 64-bit `time_t` on 32-bit archs with system libarchive
16cc3e25d4 Utilities: Select bundled or external dependencies very early

Commit 1b9e8f833f (Linux: Compile with 64-bit time_t even on 32-bit
architectures, 2025-06-26, v4.1.0-rc2~16^2) broke running with a
system-provided libarchive that uses a 32-bit `time_t`. If CMake
is configured to build with a system libarchive, assume the user
has taken responsibility to match `time_t` sizes.

In commit e419429616 (StdIo: Restore Windows Console I/O modes on
Ctrl-C, 2025-11-26, v4.1.4~4^2) we relied on the compiler to generate a
lambda with an `operator()` for each calling convention. MSVC does
this, but the GNU compiler for MinGW does not seem to.
Exclude infrastructure added by commit 61743471d9 (ast-grep: add a rule
to find adjacent string literals in cmStrCat calls, 2025-05-15,
v4.1.0-rc1~122^2~3).
Since commit 7db3dbddb2 (VS: Suppress MSBuild default flags not
specified by project or user, 2025-06-02, v4.1.0-rc1~69^2) we suppress
the `-Zc:inline` default flag when the project/user does not specify it.
That triggers an apparent bug in VS 2019 with v142 toolset versions
before 14.29 in which MSBuild fails when both `-Zc:inline` and `-nologo`
are suppressed. This happens when `CMAKE_VERBOSE_MAKEFILE` is enabled,
such as in `try_compile` projects like our builtin compiler inspection.
Since `-nologo` is incidental, avoid suppressing it if `-Zc:inline` is
also suppressed. Limit this workaround to relevant toolset versions.

Extend commit fb3e7825f3 (StdIo: Restore Windows Console I/O modes on
exit, 2025-05-23, v4.1.0-rc1~114^2) to cover termination by Ctrl-C.

In flang, both -J and -module-dir support both joined and separate values. For
the -J option, these are of the form `-J<value>` and `-J <value>` respectively.
Once https://github.com/llvm/llvm-project/pull/168748 is committed, -module-dir
will only work with a separate value. Setting CMAKE_Fortran_MODDIR_FLAG to -J
ensures that both joined and separate styles will continue to work after that
change is made. As far as behavior is concerned, both -J and -module-dir are
aliases.
Extend commit fa3c4b6dbf (Source: Link libatomic when needed on any
Linux architecture, 2023-08-24, v3.27.5~9^2) to decide based on the
architecture targeted by the compiler, known since CMake 4.1.
Use `CMAKE_SYSTEM_PROCESSOR` only as a fallback for older versions.

Also revert commit 9702a01dc9 (Help: string(LENGTH): Fix synopsis link
to command description, 2023-12-30, v3.28.2~23^2). It was only needed
to avoid re-using a named reference that we've now removed.
