Use of C's enum command with C166 compiler

Richard Roebuck

I'm currently attempting to modify an automatic code generation
package (designed to run with MSVC/C++, WATCOM C/C++ and
Borland C) to autogenerate software compilable with the Keil
CA166 package. Of the standard files which have to be included
into the code, one of them contains the lines...

enum {
COMPLEX_INHERITED = -1,
COMPLEX_NO,
COMPLEX_YES
};

...but the C166 compiler 'seems' to be objecting to the fact that
I'm using a negative number within the enum command.

According to K & R the enum command should be declaring the
contents of the enum commands to be of type 'int' - so I can't
see what the problem is.

Can anyone shed any light on this? Where am I going wrong?


Yours (grateful in advance),


Richard Roebuck.

    For instance if it is used in array subscripting, the negative value would be an error.

    A slight side-track here, as Jon has alrady pointed out that negative indices are not wrong per se.

    With C51, I have found that it will report errors on all lines containing any array reference if there is any error in any preceding line.
    Maybe Keil's handling of the subscript operator, [], is just particularly fragile?
