I noticed that PUBLIC is refined a number of times[1]. This doesn't make much 
sense, does it? The definitions aren't always the same (some take into 
account SWIG while others don't). I'd suggest moving all these definitions to 
a central location (eg, public_csound.h), and have all files that need PUBLIC 
include this file. As a bonus track, maybe rename the macro to CSOUND_PUBLIC 
or something like that, to avoid colision with other projects. This is pretty 
simple, so I can do all this and prepare a patch[2], but I'd like input 
before doing it.

[1] A quick grep shows these files:
frontends/csladspa/csladspa.cpp
H/csound.h
interfaces/filebuilding.h
interfaces/CsoundFile.hpp

[2] Actually I already started a similar one: it includes support for 
gcc-based builds (ie: #define PUBLIC __attribute__((visibility("default"))) 
and compile with -fvisibility=hidden).
