Thanks, I see. I've updated the PHP version field accordingly.

Sorry, I couldn't tell: I have moved onto 64-bit years ago, that eliminated the
Large-File-Problem.

But I've just checked the source of zend_stream.h in 7.1.9 -- the field's name is still
'mmap', so it still might cause problem on systems where large-file-support is solved via
'#define mmap mmap64' 

Note: gcc-based systems use __asm__("mmap64"), so thex don't face this problem.

Is this still an issue with current PHP versions?

"Good" news: on AIX, compiling with large-file-support raises other
problems, too; for example there won't be function 'fopen' only function
'fopen64'

Or simply the inclusion of <sys/mman.h> could come before the inclusion of
"config.h"

Description:
------------
Compilation of main/main.c fails, the error message is:

/usr/local/src/php-5.3.9/main/main.c:1230: error: 'zend_stream' has no member named
'mmap64'
/usr/local/src/php-5.3.9/main/main.c:1230: error: 'zend_stream' has no member named
'mmap64'
/usr/local/src/php-5.3.9/main/main.c:1239: error: 'zend_stream' has no member named
'mmap64'
/usr/local/src/php-5.3.9/main/main.c:1240: error: 'zend_stream' has no member named
'mmap64'

The compilation went with largefile support (-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64
-D_LARGE_FILES), which caused sys/mman.h to define mmap as mmap64; I suppose it would work, if 

1. I compiled without largefile support (I don't like this idea)
2. The member 'mmap' of 'struct _zend_stream' had a less problematic name
('zmmap' for example)
3. Header 'zend_stream.h' included 'sys/mman.h'
4. I predefined 'mmap' as 'mmap64': -Dmmap=mmap64
5. I compiled in 64 bits (I'm afraid to do so, to be frank)

Platform: AIX 6.1 (oslevel -r = 6100-05); gcc (gcc --version = 4.4.5)
