I can not compile under Ubuntu with gcc 3.3... (?)

[mahmoodn <nt_mahmood@xxxxxxxxx>]

Hi,
I compile my program in fedora with gcc 3.3 with no problem, but when I want
to compile it with the same version under Ubuntu, it says:

mahmood@magma:~/Tools/cgal/VVc_diagram_2/demo/VVc_diagram_2$ make
g++ -I../../include -I../../../Arrangement_2/include -DNDEBUG -Wall
-frounding-math          -I/usr/include/qt3            -c MD_demo.cpp
cc1plus: error: unrecognized option `-frounding-math'
make: *** [MD_demo.o] Error 1

what does this error mean? I do not have "-frounding-math" option in
makefile. Here is the makefile:

# Created by the script create_makefile

# This is the makefile for compiling a CGAL application.

ifndef CGAL_MAKEFILE
CGAL_MAKEFILE = /usr/share/cgal/makefile
endif
include $(CGAL_MAKEFILE)
