    Declaration of the timestamp variable was failing on 64-bit system (2/4/11)

sys/mwcs/wftnx.x
sys/mwcs/wfzpx.x
sys/mwcs/wfzpn.x
    The interative inversion method could runaway leading to an arithmetic
    exception.  Added a maximum change to each iteration to avoid this.

     The earlier update to fix the double-precision problem left a debug
     value in the generic code that was never updated in the patch build.
     This meant that zero pixels in FITS files were being interpreted as
     128 (the debug value).  (2/17/11)

pkg/dataio/fits/fits_rpixels.x
pkg/dataio/fits/fits_wpixels.x
    Buffer sizes were being computed using SZ_INT instead of SZ_INT32 (2/18/11)

    An earlier change to the token declarations had the strange effect of
    changing the processing of string comparison.  This effectively broke
    tasks like HSELECT.  Fell back to the earlier (and original) code until
    this is better understood, however it doesn't appear to be releated to
    the XYACC changes.  (2/18/11)

pkg/images/tv/imexamine/imexam.h
    The coordinates arrays in the main structure were improperly indexed
    with the P2R macro (2/20/11)
