ext/gd/gd_ctx.c: In function '_php_image_stream_putc': error: 'struct gdIOCtx' has no member named 'data'

Dear PHP folks :

I am trying to build php 5.4.11 with the GD extension and running into an error where both 

GCC 4.7.2 and Oracle Studio 12.3 claim that :

"/usr/local/build/php-5.4.11_SunOS5.10_sparcv9+GD.001/ext/gd/gd_ctx.c", line 51: error: improper member use: data
"/usr/local/build/php-5.4.11_SunOS5.10_sparcv9+GD.001/ext/gd/gd_ctx.c", line 58: error: improper member use: data
"/usr/local/build/php-5.4.11_SunOS5.10_sparcv9+GD.001/ext/gd/gd_ctx.c", line 67: error: improper member use: data
"/usr/local/build/php-5.4.11_SunOS5.10_sparcv9+GD.001/ext/gd/gd_ctx.c", line 68: error: improper member use: data
"/usr/local/build/php-5.4.11_SunOS5.10_sparcv9+GD.001/ext/gd/gd_ctx.c", line 69: error: improper member use: data
"/usr/local/build/php-5.4.11_SunOS5.10_sparcv9+GD.001/ext/gd/gd_ctx.c", line 153: error: improper member use: data

or in the case of GCC 4.7.2 we see :

/usr/local/build/php-5.4.11_SunOS5.10_sparcv9+GD.001/ext/gd/gd_ctx.c: In function '_php_image_stream_putc':

At line 48 in ext/gd/gd_ctx.c we see function _php_image_stream_putc :

static void _php_image_stream_putc(struct gdIOCtx *ctx, int c) {
char ch = (char) c;
php_stream * stream = (php_stream *)ctx->data;
TSRMLS_FETCH();
php_stream_write(stream, &ch, 1);
}

Which seems to use the GD IO context struct gdIOCtx thus :

Looking in ./ext/gd/libgd/gd_io.h I see at line 10 :

typedef struct gdIOCtx {
int (getC)(struct gdIOCtx);
int (getBuf)(struct gdIOCtx, void*, int);

    void    (*putC)(struct gdIOCtx*, int);
    int     (*putBuf)(struct gdIOCtx*, const void*, int);

    int     (*seek)(struct gdIOCtx*, const int);
    long    (*tell)(struct gdIOCtx*);

    void    (*gd_free)(struct gdIOCtx*);

    void    *data;

} gdIOCtx;

So I am baffled as there it is, a nice void pointer.

I make the one line change :

node002 $ diff ext/gd/gd_ctx.c_backup ext/gd/gd_ctx.c
21a22

#include "gd_io.h"

then run configure :

node002 $ ./configure --with-apxs2=/usr/local/bin/apxs --with-mysql=/opt/mysql/mysql \

etc etc .... however I can look the other way on those for now.

The real issues, the so called errors, are in the gd extension :

gmake: *** [ext/gd/gd.lo] Error 1

This is just a mystery to me because this looks fine :

49  static void _php_image_stream_putc(struct gdIOCtx *ctx, int c)  {
50          char ch = (char) c;
51          php_stream * stream = (php_stream *)ctx->data;
52          TSRMLS_FETCH();
53          php_stream_write(stream, &ch, 1);
54  }

The struct gdIOCtx has the void ptr data.

Has anyone built in the GD extension lately ? Am I seeing a valid error here ?
