Subject: Problems when building C extensions with ruby 1.8.7

Hello to everyone. Today, I just tried installing ruby 1.8.7, and now I'm 
having problems compiling a C extension for it. In particular, the extension 
was svn version of korundum/qt-ruby, which compiled correctly with ruby 1.8.6. 
Now, I'm getting this message:

/home/stefano/Desktop/kdebindings/ruby/qtruby/src/Qt.cpp: In function 'VALUE 
method_missing(int, VALUE*, VALUE)':                      
/home/stefano/Desktop/kdebindings/ruby/qtruby/src/Qt.cpp:715: error: invalid 
conversion from 'const char*' to 'char*'

The line in question reads:

char * methodName = rb_id2name(SYM2ID(argv[0]));

I thought that ruby-1.8.7 and ruby 1.8.6 had the same C API, but apparently 
it's not so. Does anyone know more about similar issue? Should I report it to 
the qtruby developers or is it a bug in ruby itself?
