           Summary: Generated file 'cairo-features.h' in distribution
                    causes #error in out-of-tree build for quartz
           Product: cairo
           Version: 1.8.10
          Platform: x86 (IA32)
        OS/Version: Mac OS X (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: quartz backend

When trying to compile cairo 1.8.10 on Mac OS for the Quartz backend, I get:

# error Cairo was not compiled with support for the quartz backend

in src/cairo-quartz-private.h

The reason is that the compile uses the file src/cairo-features.h that came
with the distribution, and not the file with the same name that was generated
by configure. Since I'm compiling in a different directory than the source
directory, the configure output file doesn't overwrite the distributed one.

The fix is obvious: just don't put cairo-features.h in the distribution file.

Also, the #error shown above is misleading: Cairo was not /compiled/ without
support for the Quartz backend; it was /configured/ without support for the
Quartz backend.

Thus, I suggest to change the #error to:

# error Cairo was not configured with support for the quartz backend
