I was building a software on CentOS 5.4 and got this:

/usr/include/php/main/streams/php_stream_filter_api.h:65: error: comma at end of enumerator list

I took a look at header and found this:

typedef enum { PSFS_ERR_FATAL, /* error in data stream */ PSFS_FEED_ME, /* filter needs more data; stop processing chain until more is available */ PSFS_PASS_ON, /* filter generated output buckets; pass them on to next in chain */ } php_stream_filter_status_t;

Removing comma after PSFS_PASS_ON everything back to normal.
