Link warning for "_dhf tentative"

I'm getting the following link error and wanted to get some input on how
bad this is:

ld: warning for symbol _dhf tentative definition of size 48 from
/Volumes/Projects/Libs/mylibrary.a(sourcecode.o) is being replaced by a
real definition of size 40 from
/Volumes/Projects/Libs/mylibrary.a(sourcecode2.o)

(source filenames have been changed for non-disclosure reasons but the two
.o files are different and linked to the same static libary).

The static library is an older one that was built from Xcode 2.4.x. I
haven't changed this library in over a year but my Xcode 3.x project is
starting to give me this warning.

My question is whether this is something I need to worry about, and if so
what I can do about it. Building the static library in Xcode 3.x is not
something very convenient to do so I would like to keep the Xcode 2.4.x
version if possible.
