Starting with Modelsim 6.2, Modelsim has made the vopt flow the default flow in their SE product lines. The problem you might see is the designs failing in 6.2x version while it works in Modelsim 6.1x version.
Solution
Turn off the optimizations by using the "-novopt" switch for vcom,vlog and vsim command line while using Modelsim SE only.Related Solution record - http://www.xilinx.com/xlnx/xil_ans_display.jsp?iLanguageID=1&iCountryID=1&getPagePath=24293
