Looks like this is the result of inappropriate name mangling.  Compile
with -save-temps and look for occurrences of this symbol in the
preprocessed source (*.ii).  Then, complain to the maintainer of the
file that contains that declaration (look for a line starting with `#'
before that declaration, in the preprocessed file) that the
declaration should declare this symbol as extern "C".  And note that
the C library is not part of GCC, so the maintainers of the culprit
header file are not the maintainers of GCC.
