--- Comment #54 from David McNeill davemc@mcpond.co.nz 2009-10-10 05:18:31 --- SetMapperFlags is in gdi32 in font.c
It is used for matching old raster fonts to printers, and is irrelevant under TrueType fonts.
It is not being asked to do anything because the second parameter is 0x00000000 in all the fixme output, so it would likely not modify anything anyway. The return value is always 0, which matches the input, so nothing is lost there.
So the fixme appears harmless in this instance.
Other possibilities are that MYOB mis-uses SetMapperFlags to do something else undocumented or unusual, or, MYOB uses some ancient raster font code that was written before TrueType, and that has to succeed for something else to work.
So, the debugging will have to continue at a deeper level.
