  4. Subject: [PATCH] ext/opcache: fix detection of shm/mmap
  5. The detection of sysvipc and mmap doesn't work well when cross-compiling,
  6. so I decided to only check for the availability of the functions involved.
  7. This is not a clean solution, but works for now(tm) :-)
  8. It should be discussed with upstream to find a better solution.
  9. This solves the issue reported at
  10. https://github.com/openwrt/packages/issues/1010
  11. and makes opcache usable on OpenWrt.
  12. Signed-off-by: Michael Heimpold <mhei@heimpold.de>
