* Fixed printing of version number in ccache --version.
- Changes for version 3.4.0:
* The compiler option form --sysroot arg is now handled like the
documented --sysroot=arg form.
* Added support for caching .su files generated by GCC flag
-fstack-usage.
* ccache should now work with distcc’s “pump” wrapper.
* The optional unifier is no longer disabled when the direct mode
is enabled.
* Added support for nvcc compiler options --compiler-bindir/-ccbin,
--output-directory/-odir and --libdevice-directory/-ldir.
* Boolean environment variable settings no longer accept the
following (case-insensitive) values: 0, false, disable and no.
All other values are accepted and taken to mean “true”. This is
to stop users from setting e.g. CCACHE_DISABLE=0 and then
expect the cache to be used.
* Improved support for run_second_cpp = false: If combined with
passing -fdirectives-only (GCC) or frewrite-includes (Clang) to
the compiler, diagnostics warnings and similar will be correct.
* An implicit -MQ is now passed to the preprocessor only if the
object file extension is non-standard. This should make it
easier to use EDG-based compilers (e.g. GHS) which don’t
understand -MQ.
* ccache now treats an unreadable configuration file just like a
missing configuration file.
* Documented more pitfalls with enabling hard_links
(CCACHE_HARDLINK).
* Documented caveats related to colored warnings from compilers.
* File size and number counters are now updated correctly when
