/* Do NOT use #ifdef CVC4_PROOF to check if proofs are enabled.
* We cannot assume users will use -DCVC4_PROOFS if they have a proofs build.
* The preferred way of checking that proofs are enabled is to use:
* #if IS_PROOFS_BUILD
* ...
* #endif
*
* The macro IS_PROOFS_BUILD is defined in base/configuration_private.h
*
* This has the effect of forcing that location to have included this header
* *before* performing this test. This includes C preprocessing expansion.
* This forces the inclusion of "cvc4_private.h". This is intentional!
*
* See bug 688 for more details:
* http://cvc4.cs.nyu.edu/bugs/show_bug.cgi?id=688
*
* If you want to check CVC4_PROOF, you should have a very good reason
* and should list the exceptions here:
* - Makefile.am
* - proof/proofs.h
* - base/configuration_private.h
