[MacOS10.4.10, wxMac2.8, gcc 4.0.1] Resuscitating an old thread: "Automating" the use of wx-config

[David Goldsmith]

On a hunch, I tried replacing --cppflags w/ -cxxflags and got a whole 
slew of compile errors - many steps back, but a big step forward???  
Also, I remembered: is _the_ problem (semi-rhetorical question: I know 
it's _a_ problem) that I'm using main, not declaring a wx.App?  Thanks!
