[packages/Firebird.git] / parallel-build.patch

Description: allow building with make -jN
 without this there are sporadic segmentation faults
 .
 it seems that when gpre opens a database, it clashes with other gpre
 processes that have the database open. perhaps this is because at
 this stage of the build the compiled firebird engine lacks ability for
 synchronisation. So, wrap all engine-using calls with a lock file
