Hello!
During compilation of Vim 7.0 under AIX (5.1 or 5.2) I get the next error:
"message.c", line 4180.1: 1506-191 (E) The character # is not a valid C
source character.
"message.c", line 4180.2: 1506-046 (S) Syntax error.
"message.c", line 4182.1: 1506-191 (E) The character # is not a valid C
source character.
"message.c", line 4185.1: 1506-191 (E) The character # is not a valid C
source character.
"message.c", line 4185.2: 1506-275 (S) Unexpected text endif encountered.
Referred lines contain preprocessor directives:
char *q = memchr(str_arg, '\0',
##if SIZEOF_INT <= 2
precision
#else
precision <= (size_t)0x7fffffffL ? precision
: (size_t)0x7fffffffL
#endif
These directives are not compilable because function memchr() used in
this code fragment on AIX is redefined as macro (see the fragment of the
file /usr/include/string.h below):
/*
* The following macro definitions cause the XLC compiler to inline
* these functions whenever possible.
*/
#ifndef __cplusplus
#ifdef __STR__
# define strcpy(__s1,__s2) __strcpy(__s1,__s2)
# define strcmp(__s1,__s2) __strcmp(__s1,__s2)
string.h = (/usr/include)
# ifndef __STR31__
# define strlen(__s1) __strlen(__s1)
# define strchr(__s1,__c) __strchr(__s1,__c)
# define strrchr(__s1,__c) __strrchr(__s1,__c)
# define strcat(__s1,__s2) __strcat(__s1,__s2)
# define memchr(__s1,__c,__n) __memchr(__s1,__c,__n)
# define memcpy(__s1,__s2,__n) __memcpy(__s1,__s2,__n)
# define memmove(__s1,__s2,__n) __memmove(__s1,__s2,__n)
# define memcmp(__s1,__s2,__n) __memcmp(__s1,__s2,__n)
# define memset(__s1,__c,__n) __memset(__s1,__c,__n)
I don't know exactly is it correct that the compiler does use this
section for this moment.
I successfully applied the next workaround:
#if SIZEOF_INT <= 2
char *q = memchr(str_arg, '\0',
precision
);
#else
char *q = memchr(str_arg, '\0',
precision <= (size_t)0x7fffffffL ? precision
: (size_t)0x7fffffffL
);
#endif
Use it if you have no objections.
Thanks.
