解决AIX5.3上Oracle10g Pro*C编译问题，记录如下：

1. OracleTemplate.mk.AIX

PROCFLAGS增加：define=_POSIX_SOURCE define=__64BIT__

2. Libxml/encoding.h

＃i nclude <iconv.h>改为＃i nclude <libxml/iconv.h>

3. HttpClient.pc

增加：

typedef struct fd_set

{

        long fds_bits[__NUM_ENTRIES];  /* bitmask for open file descriptors */

} fd_set;
