FreeBSD 3.4
>Description:
FreeBSD 3.4's <ctype.h> defines a macro _T. Then when _T is used as a template parameter (in include/g++-3/std/mask_array.h and /include/g++-3/std/slice_array.h), it is expanded to an implementation-defined constant and bad things happen.
>How-To-Repeat:
#include <valarray>
>Fix:
sed s/_T/T/g on slice_array.h and mask_array.h
