Patch for build gmagick on mac osx 10.6(snow leopard)

在mac osx 10.6.2(snow leopard)编译gmagick失败. 错误如下:

ld: duplicate symbol _php_gmagick_sc_entry in .libs/gmagick_methods.o and .libs/gmagick_helpers.o
collect2: ld returned 1 exit status
make: *** [gmagick.la] Error 1

感觉很奇怪,因为在centos上没问题. 检查了下gmagick_methods.c和gmagic_helpers.c 也没有重复定义啊.

$ nm .libs/gmagick_methods.o |grep _php_gmagick_sc_entry
000000000000f570 S _php_gmagick_sc_entry
$ nm .libs/gmagick_helpers.o |grep _php_gmagick_sc_entry
00000000000034b8 S _php_gmagick_sc_entry

Oh, ld没错, 的确是重复定义了,由于类型是S,那么还是php_gmagick_sc_entry的声明有问题.
再仔细查看了一下,果然. 由于php_gmagick_sc_entry是在php_gmagick.h中声明,而在gmagick_methods.c
和gmagic_helpers.c中都include了这个文件. 由于没有显示声明为exten导致了问题. 重新加入exten修饰符,
ok.
