Original commit message from CVS: Patch by: Andreas Henriksson <andreas at fatal dot set> * gst/nsf/Makefile.am: * gst/nsf/dis6502.h: * gst/nsf/fds_snd.c: * gst/nsf/fds_snd.h: * gst/nsf/fmopl.c: * gst/nsf/fmopl.h: * gst/nsf/gstnsf.c: * gst/nsf/log.c: * gst/nsf/log.h: * gst/nsf/memguard.c: * gst/nsf/memguard.h: * gst/nsf/mmc5_snd.c: * gst/nsf/mmc5_snd.h: * gst/nsf/nes6502.c: * gst/nsf/nes6502.h: * gst/nsf/nes_apu.c: * gst/nsf/nes_apu.h: * gst/nsf/nsf.c: * gst/nsf/nsf.h: * gst/nsf/osd.h: * gst/nsf/types.h: * gst/nsf/vrc7_snd.c: * gst/nsf/vrc7_snd.h: * gst/nsf/vrcvisnd.c: * gst/nsf/vrcvisnd.h: Update our internal nosefart to nosefart-2.7-mls to fix segfaults on some files. Fixes bug #498237. Remove some // comments, fix some compiler warnings and use pow() instead of a slow, selfmade implementation.
