Update clar from: - 1516124 (Merge pull request #97 from pks-t/pks-whitespace-fixes, 2024-08-15). To: - 0810a36 (Merge pull request #107 from pks-t/pks-sunos-compatibility, 2024-10-14) This update includes a bunch of fixes and improvements that we have discussed in Git when initial support for clar was merged: - There is a ".editorconfig" file now. - Compatibility with Windows has been improved so that the clar compiles on this platform without an issue. This has been tested with Cygwin, MinGW and Microsoft Visual Studio. - clar now uses CMake. This does not impact us at all as we wire up the clar into our own build infrastructure anyway. This conversion was done such that we can easily run CI jobs against Windows. - Allocation failures are now checked for consistently. - We now define feature test macros in "clar.c", which fixes compilation on some platforms that didn't previously pull in non-standard functions like lstat(3p) or strdup(3p). This was reported by a user of OpenSUSE Leap. - We stop using `struct timezone`, which is undefined behaviour nowadays and results in a compilation error on some platforms. - We now use the combination of mktemp(3) and mkdir(3) on SunOS, same as we do on NonStop. The most important bits here are the improved platform compatibility with Windows, OpenSUSE and SunOS.
