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.
Fixes: #27406
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.
Issue: #25546
Since commit 5420639a8d (cmExecuteProcessCommand: Replace cmsysProcess
with cmUVProcessChain, 2023-06-01, v3.28.0-rc1~138^2~8) we have not
actually terminated child processes on an `execute_process` timeout.
Similarly for other migrations from cmsysProcess to cmUVProcessChain.
Teach cmUVProcessChain clients that implement timeouts to actually
terminate remaining child processes when the timeout is reached.
