Re[2]: 4.17.86 on AIX 4.2.0.0 using IBM xlc


For what it is worth the xlc lslpp information is

Fileset  Level  State Description
xlC.C    3.1.4.0  C   C for AIX Compiler


I note that my copy of the ANSI-C Standard
ISO/IEC 9899: 1990 Programming languages-C

doesn't have the trailing comma varient in section 6.5.2.2

A colleague notes that VMS Dec C gives a warning for the idiom.

Hmm (is this a nightmare comming true?),

Looking at C manual:

6.5.2.2 Enumeration specifiers
Syntax
  enum-specifier:
    enum identifieropt { enumerator-list }
    enum identifieropt { enumerator-list , }
    enum identifier
  enumerator-list:
    enumerator
    enumerator-list , enumerator
  enumerator:
    enumeration-constant
    enumeration-constant = constant-expression

and the relevant line:

enum thread_control_capabilities {
        tc_none = 0,            /* Default: can't control thread
execution. */
        tc_schedlock = 1,       /* Can lock the thread scheduler. */
        tc_switch = 2,          /* Can switch the running thread on
demand. */
};

So, what to do about this one?
