deploy/src/plugin/win32/regutils/UpdateConf.cpp is included and recompiled for several install binaries. Each binary does not necessarily use all of the functions, but without the /Gy compiler option to enable function level linking along with the /OPT:REF linker option, the linker cannot eliminate functions that are never referenced. http://msdn2.microsoft.com/en-us/library/bxwfs976(VS.80).aspx

Adding -Gy to CXXFLAGS in deploy/make/plugin/regutilsmsi/Makefile reduced the size of the DLL by 8 KB.

The following use UpdateConf.cpp:
plugin/jupdate/checker - jucheck.exe
plugin/jupdate/scheduler - jusched.exe
plugin/regutils - regutils.dll
plugin/regutilsmsi - regutilsmsi.dll
