Without explicitely including <cstdlib>, compiling some files including store/source/storbase.hxx (such as store/source/storpage.cxx which includes it through store/source/storpage.hxx) will result in errors: error: ‘malloc’ is not a member of ‘std’ and error: ‘free’ is not a member of ‘std’ This patch simply adds the necessary include.
