Try this patch.  It solved the compile error for me, but I'm not entirely sure all the features are right, since the php developers I work with haven't tested it out completely.

If this fixes the compile time problem, but causes other errors, please let me know, as that would be valuable information for me.

I moved ZEND_ARGINFO declarations from headers to rrd.c. I think it solves:
arginfo_rrd_info
arginfo_rrd_graph
arginfo_rrd_create
arginfo_rrd_update
problems.

I don't know why there is some problem with multiple definition of `arginfo_construct', because both `arginfo_construct' are declared in *.c via "ZEND_ARGINFO" macros, which are shortcuts for "static const arginfo_construct[]" declaration. I think it's correct to have same static const declaration in two modules.

Try to use current trunk and let me know if any warnings please.

Hello,

It's works with the patch =)

Thanks a lot !

patch from ja391045 at gmail dot com maybe solves compiling problems, but it's like quick fix. 

Solution with moving args_info declaration into rrd.c is more clear I think.

I also got answer in pecl mailing list about multiple definition of `arginfo_construct' problem. It's problem only for php < 5.3. I'll try to fix soon.

I made final fix for multiple definition of
`arginfo_construct' problem, so bug is completely solved (in trunk), but I don't tested in 5.2. Reopen if necessary.
