Use the more portable sysfs node /sys/devices/system/cpu/cpuX/cpufreq/scaling_cur_freq
to get the CPU frequency.
In case of an error fall back to /proc/cpuinfo .
Also use a fixed width of 4 for the frequency to avoid position jumps
in case the frequency moves in the range 900-1100 MHz.
For a process with a very long command, especially with many long
command line arguments, inspecting the command and its arguments could
become inconvenient.
Meanwhile htop supports the concept of "screen", or window, which is
extended here to create a dedicated "CommandScreen", making it possible
to display the command of the selected process in a separate window
meanwhile being wrapped into multiple lines.
Another benefit of using a command screen is, the user can navigate
through the wrapped lines of the command and perform actions like
searching and filtering.
unsigned integer overflows are well-defined, but they might point to a counting issue.
Having the code free of unsigned overflows makes it easier to spot potential bugs.
Action.c:332:27: runtime error: implicit conversion from type 'int' of value -1 (32-bit, signed) to type 'uid_t' (aka 'unsigned int') changed the value to 4294967295 (32-bit, unsigned)
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior Action.c:332:27 in
`-m` was added as short option for `--no-mouse`, this is inconsistence
to the rest of the cli since otherwise the short options to disable a
feature are capital letters. Therefore this commit renames the option to
`-M`.
This commit also documents the option in the man page.
It might be working, but lets rather not modify getopt's global variable
`optarg`.
Also there is no need to call `getenv("USER")`, just use `geteuid()`.
unsigned overflow is well defined, but creates noise when using
sanitizers. unsigned overflow can be a symptom of logic issues of
counter, so its reasonable to use.

linux/LinuxProcessList.c:64:78: runtime error: unsigned integer overflow: 4 - 136 cannot be represented in type 'unsigned int'
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior linux/LinuxProcessList.c:64:78 in
- enable warnings in autogen script
- drop unused m4/ directory usage
- drop AC_TYPE_SIGNAL:
C99 guarantees the signal return type to be void
- drop AC_CHECK_FILE of procdir:
most of the time compilation is done on a different system than htop is run
and there is a runtime check in place
- improve linux_affinity corss compile logic:
use fourth argument instead of pre-test
