Sorting vectors

[Joe Neeman]

flower/include/std-vector.hh contains the comment:

/* FIXME: the COMPARE functionality is broken?  */

and the version of vector_sort that makes use of the STL sort algorithm is 
commented out. But based on my reading of the SGI STL manual[1], you are just 
using the wrong compare function. You use a compare function like

int compare_int (const int &a, const int &b) {return sign (a - b);}

but it expects

bool compare_int (const int &a, const int &b) {return a < b;}

(which is what the STL function less<T> does (if the class that you are 
comparing has a "<" operator))
