- Removed #pragma warnings from cmdlib.h and fixed the places where they were still triggered. These #pragmas were responsible for >90% of the GCC warnings that were not listed in VC++. - Fixed one bug in the process: DSeqNode::m_Atten was never adjusted when the parameter handling of the sound functions for attenuation was changed. Changed m_Atten to a float and fixed the SNDSEQ parser to set proper values. Also added the option to specify attenuation with direct values in addition to the predefined names. SVN r1583 (trunk)
