Sounds good! Here my proposed changes:

  1. I'll add to buildtools/conf/MonetDB.m4

   AC_CHECK_LIB(m, main, [ MATH_LIBS="-lm" ] )

  2. I'll look after -lm in

   MonetDB4/src/modules/calibrator/Makefile.ag:    LDFLAGS = -lm
   MonetDB4/src/modules/calibrator/Makefile.ag:    LIBS = -lm
   MonetDB4/src/modules/contrib/Makefile.ag:       LDFLAGS = -lm
   MonetDB4/src/modules/contrib/Makefile.ag:       LDFLAGS = -lm
   MonetDB4/src/modules/mnetcdf/Makefile.ag:       LDFLAGS = -lm $(NETCDF_LIBS)
   MonetDB4/src/modules/plain/Makefile.ag:         LDFLAGS = -lm
   MonetDB5/src/modules/atoms/Makefile.ag:         LIBS = $(MONETDB_LIBS) -lbat -lstream -lm \
   MonetDB5/src/modules/kernel/Makefile.ag:        LDFLAGS = -lm
   MonetDB5/src/modules/mal/Makefile.ag:           LIBS = ../../mal/libmal $(MONETDB_LIBS) -lbat -lstream -lm \
   MonetDB5/src/optimizer/Makefile.ag:             LDFLAGS = -lm

     and substitute it with LIBS = ... $(MATH_LIBS)

  3. I'll add to MonetDB/conf/rules.msc:
