texinfo-4.11 on HP-UX v11.00 - "#define __(s) getdocumenttext(s)"

[Gary E. Barnes]

The macro __(s) defined in makeinfo/makeinfo.h conflicts with the various
operating system defined macros __(arg) defined in the HP include files.

For example, from /usr/include/sys/stdsyms.h

    /* macros for simplifying prototype declarations */
    #undef __
    #if defined(_PROTOTYPES) 
    #define __(arg) arg
    #else
    #define __(arg) ()
    #endif

This prevents makeinfo/cmds.c from compiling for example.

There is no error in /usr/include/time.h.  Rather there is a use of the
__(arg) macro.  This code fragment from time.h,

+------------------------------------------------------------------------------
| #if !defined(__STDC_32_MODE__)
| extern  hrtime_t        gethrtime();
| #endif
|            extern int get_expiration_time __((struct timespec *,struct 
timespec *));
| #ifdef __cplusplus
|    }
| #endif /* __cplusplus */
+------------------------------------------------------------------------------
expands into the text that gcc is complaining about,
+------------------------------------------------------------------------------
| extern  hrtime_t        gethrtime();
| 
|            extern int get_expiration_time getdocumenttext( (struct timespec 
*,struct timespec *) ) ;
