-+* 2000-04-13 Pierangelo Masarati <masarati@×××××××××××.it>

-+* 2000-??-?? Pierangelo Masarati <masarati@×××××××××××.it>
-+ - changed the struct pair in sparse.h to avoid conflicts with C++ stl
-+ - added some helpers for adding and subtracting coefs from sparse matrices
-+ - WARNING: in C++ the macro `catch' conflicts with the exception handling
-+   keyword; I temporarily fixed the problem by #undef-ining it after including
