Maybe.  pfSqrt is defined in a header file and that header file in
included in several other header files.  I stopped following the chain
after a few links but it is likely that you have two sources that
include com_math.h either directly or indirectly.

Generally, header file should not define things (the common exception
being inline functions).  Try putting "extern" on the definition and
finding a .c file in which it is natural to actually define the pointer.
