  Log Message:
  -----------
  Fix pointer to integer (to pointer) casting warnings in audioconvert.

Don't cast a pointer to an integer, add a number to it, and then cast
it back to a pointer.  This transformation is not transparent to the
compiler, and it can lose potential optimizations chances.  Instead
cast it to a pointer to a uint8_t (width of one byte) and then do the
addition directly to the pointer.

  Log Message:
  -----------
  Fix loss of precision warning in signalmonitor.cpp.

Casting from a pointer to a "long" is only valid if they contain the
same number of bits.  Instead use the uintptr_t type, which is an
integer type that is guaranteed to have the same number of bits as a
pointer.

    M mythtv/libs/libmythtv/recorders/RTjpegN.h

  Log Message:
  -----------
  Use aligned new in RTjpeg.cpp instead of manual alignment.

This simplifies the code, as well as eliminating warnings about
casting pointers to integers and back to pointers.
