Description:
------------
I found a small coding bug in cairo_surface.c.

Trying to do a "make" of the cairo code I get an error message on line 647 of cairo_surface.c (transcript partially truncated at front):-

Downloads/pecl-cairo/cairo_surface.c: In function ‘php_cairo_get_surface_ce’:
Downloads/pecl-cairo/cairo_surface.c:647: error: ‘CAIRO_SURFACE_TYPE_RECORDING’ undeclared (first use in this function)
Downloads/pecl-cairo/cairo_surface.c:647: error: (Each undeclared identifier is reported only once
Downloads/pecl-cairo/cairo_surface.c:647: error: for each function it appears in.)

When I check the relevant section of the source file (cairo_surface.c) I see the following (in part):

================================================== ========================
#ifdef CAIRO_HAS_SVG_SURFACE
case CAIRO_SURFACE_TYPE_SVG:
type = cairo_ce_cairosvgsurface;
break;
#endif

#ifdef CAIRO_HAS_PS_SURFACE
case CAIRO_SURFACE_TYPE_PS:
type = cairo_ce_cairopssurface;
break;
#endif

#ifdef CAIRO_HAS_PS_SURFACE
case CAIRO_SURFACE_TYPE_RECORDING:
type = cairo_ce_cairorecordingsurface;
break;
#endif
==================================================

The #ifdef CAIRO_HAS_PS_SURFACE has been duplicated [in error].



Test script:
---------------
I was able to fix this simply by changing the *second* instance of the ifdef statement to read:-

#ifdef CAIRO_HAS_RECORDING_SURFACE
                case CAIRO_SURFACE_TYPE_RECORDING:
                        type = cairo_ce_cairorecordingsurface;
                        break;
#endif

[i.e. replace _PS_ with _RECORDING_ ] 

That seems to solve the problem and I can get the source to compile and install cleanly from that point onwards. 

I hope I'm reporting this at the right place!!!
