Possible error in g++ 970907

[System Source]

While compiling octave 2.0.9 I have hit the following problem.  This
compiles fine with gcc-2.7.2.3.f.2.

/usr/local/pkg/egcs/include/g++/function.h: In function `double * negate(const double *, int)':
/usr/local/pkg/egcs/include/g++/function.h:96: previous non-function declaration `template <class T> struct negate<T>'
