Dear sirs,

I tried to install gcc-2.95.1 on solaris 2.6.
During complilation I got the following error:

  /home/michael/install/gcc-2.95.1/gcc/xgcc
-B/home/michael/install/gcc-2.95.1/gcc/

gmake[1]: *** [valarray.o] Error 1
gmake[1]: Leaving directory
`/home/michael/install/gcc-2.95.1/sparc-sun-solaris2.6/libstdc++'

I checked the /usr/include/math.h file and saw the 'struct exception' is
defined as:
struct exception {
        int type;
        char *name;
        double arg1;
        double arg2;
        double retval;
};
but in the <gcc-2.95.1 install dir>/gcc/include/exception file 'class
exception' is defined:

class exception {
public:
  exception () { }
  virtual ~exception () { }
  virtual const char* what () const;
};

Could you check this problem ?
