When Intel CET is enabled, we need to include <cet.h> in assembly codes
to mark Intel CET support and add _CET_ENDBR to indirect jump targets.
Tested on Intel Tiger Lake under CET enabled Linux.
The syntax "if(DEFINED CACHE{FOO})" requires CMake 3.14.
In some other places the code treats the cache variables
like normal variables already (${FOO} or if(FOO) is used,
not ${CACHE{FOO}).
Thanks to ygrek for reporting the bug on IRC.
I don't want to use \c in macro arguments but groff_man(7)
suggests that \f has better portability. \f would be needed
for the .TP strings for portability reasons anyway.
Thanks to Bjarni Ingi Gislason.
A few are simply omitted, most are converted to "for example"
and surrounded with commas. Sounds like that this is better
style, for example, man-pages(7) recommends avoiding such
abbreviations except in parenthesis.
Thanks to Bjarni Ingi Gislason.
Docs of ancient troff/nroff mention \(em (em-dash) but not \(en
and \- was used for both minus and en-dash. I don't know how
portable \(en is nowadays but it can be changed back if someone
complains. At least GNU groff and OpenBSD's mandoc support it.
Thanks to Bjarni Ingi Gislason for the patch.

DJGPP 2.05 added support for thousands separators but it's
broken at least under WinXP with Finnish locale that uses
a non-breaking space as the thousands separator. Workaround
by disabling thousands separators for DJGPP builds.
The comment didn't match the value of RC_SYMBOLS_MAX and the value
itself was slightly larger than actually needed. The only harm
about this was that memory usage was a few bytes larger.
Normally, if po4a isn't available, autogen.sh will return
with non-zero exit status. The option --no-po4a can be useful
when one knows that po4a isn't available but wants autogen.sh
to still return with zero exit status.
Seems that the phrase "add more quotes" from sh/bash scripting
applies to CMake as well. E.g. passing an unquoted list ${FOO}
to a function that expects one argument results in only the
first element of the list being passed as an argument and
the rest get ignored. Adding quotes helps ("${FOO}").
list(INSERT ...) is weird. Inserting an empty string to an empty
variable results in empty list, but inserting it to a non-empty
variable does insert an empty element to the list.
Since INSERT requires at least one element,
"${CMAKE_THREAD_LIBS_INIT}" needs to be quoted in CMakeLists.txt.
It might result in an empty element in the list. It seems to not
matter as empty elements consistently get ignored in that variable.
In fact, calling cmake_check_push_state() and cmake_check_pop_state()
will strip the empty elements from CMAKE_REQUIRED_LIBRARIES!
In addition to quoting fixes, this fixes checks for the cache
variables in tuklib_cpucores.cmake and tuklib_physmem.cmake.
Thanks to Martin Matuška for testing and reporting the problems.
These fixes aren't tested yet but hopefully they soon will be.
This does *NOT* replace the Autotools-based build system in
the foreseeable future. See the comment in the beginning
of CMakeLists.txt.
So far this has been tested only on GNU/Linux but I commit
it anyway to make it easier for others to test. Since I
haven't played much with CMake before, it's likely that
there are things that have been done in a silly or wrong
way and need to be fixed.
tuklib_cpucores.c and tuklib_physmem.c don't include <sys/types.h>
even via other files in this package, so clearly that header isn't
needed in the tests either (no one has reported build problems due
to a missing header in a .c file).
Appears that this file used to get included as a side effect of
gettext. After the change to gettext version requirements this file
no longer got copied to the package and so the build was broken.
strerror() needs <string.h> which happened to be included via
tuklib_common.h -> tuklib_config.h -> sysdefs.h if HAVE_CONFIG_H
was defined. This wasn't tested without config.h before so it
had worked fine.
The previous commit broke crc32_tablegen.c.
If the whole package is built without config.h (with defines
set on the compiler command line) this should still work fine
as long as these headers conform to C99 well enough.
string.h is used unconditionally elsewhere in the project and
configure has always stopped if limits.h is missing, so these
headers must have been always available even on the weirdest
systems.
There is no specific reason for this other than blocking
the most ancient versions. These are still old:
Autoconf 2.69 (2012)
Automake 1.12 (2012)
gettext 0.19.6 (2015)
Libtool 2.4 (2010)
This bumps the version requirement from 0.19 (from 2014) to
0.19.6 (2015).
Using only the old AM_GNU_GETTEXT_VERSION results in old
gettext infrastructure being placed in the package. By using
both macros we get the latest gettext files while the other
programs in the Autotools family can still see the old macro.
