#668 macro produces code which won't compile

[William Fulton]

1.3.27 ignored the following:

#define H_SUPPRESS_SCALING_MAGIC (('s'<<24) |
('u'<<16) | ('p'<<8) | ('p'))

1.3.29 produces code which won't compile

Sadly this patch causes worse regressions than the problem
fixed, so I've backed it out.

This was finally fixed last year in 3.0.11:

            Patch #781 - Fix wrapping of C compound expressions containing char constants
            in quotes such as:

              #define H_SUPPRESS_SCALING_MAGIC (('s'<<24) | ('u'<<16) | ('p'<<8) | 'p')

              enum DifferentTypes {
                typecharcompound='A'+1,
                typecharcompound2='B' << 2
              };
