Hi Orson,

I tested your patch without any issue on W7 32 bits and gdb.

With -DBUILD_SMALL_DEBUG_FILES=ON option, the binaries are about 20 time
smaller than without this option.

In fact on my 32 bits install, without this option, I cannot load pcbnew
from Kicad or with gdb and load a medium complexity board: I am running
out of memory.

In countries using a comma as FP separator, there is a problem:
When loading a bitmap, and perhaps some config files, a wxASSERT is
displayed (see attached copy)
I tried to fix this wxWidgets alert, but no luck.
