work around a bug in dtrace - it strips const from function parameters
With usedtrace this caused:
- build failures under g++ (OS X)
- const qualification warnings with gcc (OS X)
The workaround simply adds const to char * parameters if not already
present.
The bug in dtrace was apparently reported to Sun in 2006:

Mozilla ran into the same problem:
