Love that 3.0!!!. Integration of gdb and edit is a big improvement
over 2.1. One thing that pleased me is that if I insert lines in a
source I'm stepping around in, the step still gets the line numbers
correct!
I believe that the "data" method of NXdata.h and NXBitmapImageRep in 3.0
together break the rule that methods with the same name must have the same
return value. The compiler says:
Spectrogram.m:181: warning: multiple declarations for method `data'
/NextDeveloper/Headers/machkit/NXData.h:23:
using `-(void *)data'
/NextDeveloper/Headers/appkit/NXBitmapImageRep.h:53:
also found `-(char unsigned *)data'
The documentation of each agrees with its respective header files. What's
the scoup?
Do others find the same thing? (perhaps my upgrade failed)
Is this also true on 2.1 (but now the compiler checks more) ?
What's the cleanest workaround? (my take is to change
NXBitmapImageRep.h)

P.S.:
The program which does this does two non-standard things, neither of which
"should" cause a problem:
1. The program uses 2.1 optimization of importing just those specific
include files that are needed (rather than using appkit/appkit.h).
2. The program uses the MusicKit, with header files retained from 2.1.
