Update of /cvsroot/monetdb/buildtools/conf
In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv18414/buildtools/conf
Modified Files:
MonetDB.m4
Log Message:
When configured with --enable-strict, let gcc also complain about undefined
macros:
`gcc -Wundef`.
However, some bison generated code apparenly inherently contains/uses undefined
marcos;
hence, we locally overrule -Wundef by -Wno-undef in those cases.
