bug#23003: 25.1.50; --with-x-toolkit options cause the build to fail.

[Keith David Bershatsky]

I built few more times this evening and now believe the following to be true:


1.  The patch you proposed resolves the following issue with gtk3 in the master 
branch, which cannot be resolved absent applying the patch.

    gtkutil.c:521: warning: comparison is always false due to limited range of 
data type
    gtkutil.c:521: warning: comparison is always false due to limited range of 
data type
      CC       emacsgtkfixed.o
    emacsgtkfixed.c:36: error: redefinition of typedef 'EmacsFixedPrivate'
    emacsgtkfixed.h:32: error: previous declaration of 'EmacsFixedPrivate' was 
here
    emacsgtkfixed.c:37: error: redefinition of typedef 'EmacsFixedClass'
    emacsgtkfixed.h:33: error: previous declaration of 'EmacsFixedClass' was 
here
    make[1]: *** [emacsgtkfixed.o] Error 1
    make: *** [src] Error 2cd .


2.  The patch has nothing to do with the errors when building athena and motif. 
 Instead, running `make clean` in between builds resolves those issues:
