/* A dummy file to include wx.h. If precompiling wx.h, I
 * always start by compiling this and producing the PCH file.
 * Then subsequent source files use the PCH file.
 *
 * If precompiling wx.h for wxWindows and derived apps,
 * link dummy.obj with your program (the MSC 7 linker complains otherwise).
 *
 * This is the only convenient way I found to use precompiled headers
 * under MSC 7.
 *
 * This will produce a big PCH file.
