Bug fixes:

- Fixed build error related to zlib on systems with older make versions
  (regression in ccache 3.2.3).

- Made conversion-to-bool explicit to avoid build warnings (and potential
  runtime errors) on legacy systems.

- Improved signal handling: Kill compiler on SIGTERM; wait for compiler to
exit
  before exiting; die appropriately.

- Minor fixes related to Windows support.

- The correct compression level is now used if compression is requested.

- Fixed a bug where cache cleanup could be run too early for caches larger
than
  64 GiB on 32-bit systems.
