plugins & PCH are incompatible ...

Hello All,

In my perception, plugins and precompiled headers generation are incompatible, since when the generated PCH would be reloaded, the plugins might not be available or similar enough.

Or is there already some mechanism avoiding (or at least checking reliably) PCH generation with plugins?

The small attached patch to trunk rev 146887 (bootstrapped for C on x86_64-linux-gnu) issues an error message when plugins are used while asking for a PCH file to be written.

2009-04-28  Basile Starynkevitch  <>
   * plugin.c: Added include of "c-common.h" for pch_file.
   (initialize_plugins): Issue an error when generating PCH.

Ok for trunk?
