[svn-r3384] Purpose:
    Bug Fix
Description:
    The 'carry' variable in the general floating point-to-floating point
    conversion routine wasn't getting initialized correctly and was causing
    problems while converting certain sequences of floating point numbers
    on the Cray SV1.
Solution:
    Added 'else carry=0;' line to always reset the carry variable to a known
    value.
Platforms tested:
    Cray SV1 (killeen)
