Changeset: 6a22cb5e0f47 for MonetDB
URL: http://dev.monetdb.org/hg/MonetDB?cmd=changeset;node=6a22cb5e0f47

Branch: Apr2011
Log Message:
memory detection: fix for FreeBSD
FreeBSD has no 64-bits memory size retrieval method ( :( ), hence we'll
always be limited by the 32-bits boundary. 2GiB is always better than
0. Reorganise the logic such that we match the best, and abort
compilation if we can't find something that works.
