Summary: when using vac.C v11 get warning about redefine for
__restrict__ in zend.h
Status: Open
Type: Bug
Package: Compile Warning
Operating System: AIX
PHP Version: 5.3.14
Block user comment: N

New Comment:
The patch is "very simple". It gets rid of endless messages. However, I do not
know the importance of restrict or __restrict__
The solution may be much different.
The AIX definition from /usr/include/standards.h
is
/*
* Handle the use of the restrict keyword in non-C99 compilers
*/
#if ((__STDC_VERSION__ >= 199901L) || defined(__C99_RESTRICT))
#define __restrict__ restrict
#else
#define __restrict__
#endif
Note: there are several ways to resolve the issue of the occainsional C++
comments in C code. But experience shows that when C++ comments are being used
c89 is often not enough.
If PHP is meant to be strictly C89 code - I could change the CFLAG to get rid
of the messages - but just because gnu accepts both - with lots of help in
zend.h it seems - does not make it better than one or the other.
If PHP is meant to be "c89" rather than "c99" (with extensions) then I need to
try with different compiler flags - because langval c99ext is wrong
yes, I know I can add the flag -qcpluscmt instead - but I am told by people who
"know" compilers that what we call c++ comments is officially an extension, not
a core element.
Thank you for your consideration.

Description:
------------
"/data/prj/php-5.3.14/Zend/zend.h", line 179.10: 1506-358 (I) "__restrict__" is
defined on line 186 of /usr/include/standards.h.
Test script:
---------------
export CFLAGS='-O2 -qlangval=extc99'
./configure --prefix=/opt --sysconfdir=/etc --mandir=/usr/share/man
make
Expected result:
----------------
"/data/prj/php-5.3.14/Zend/zend.h", line 179.10: 1506-358 (I) "__restrict__" is
defined on line 186 of /usr/include/standards.h.
but MANY MANY times
