Changeset: 579c03392bcd for MonetDB
URL: http://dev.monetdb.org/hg/MonetDB?cmd=changeset;node=579c03392bcd
Modified Files:
gdk/gdk_system.mx
Branch: default
Log Message:
Only compile MT_locktrace_{start,end} when MT_LOCK_TRACE is defined.
Those functions are only ever called when MT_LOCK_TRACE is defined, so
no point having dummy functions if the symbols is not defined.
