>Description:
As described in this short thread:

  http://mail-index.netbsd.org/pkgsrc-users/2017/09/29/msg025639.html

the update of "textproc/xerces-c" prior to the pkgsrc-2017Q3 branch
causes building "games/enigma" to fail.

Looking through a recent bulk build log:

  http://mail-index.netbsd.org/pkgsrc-bulk/2017/12/22/msg015342.html

I see several other packages that directly depend on "xerces-c" and
a couple more of them fail in the same way during the build phase:

  devel/xsd
  textproc/xqilla

"textproc/xmltooling" fails during the configure phase, claiming it
can't find the xerces headers.

The failure of "textproc/xqilla" further breaks:

  databases/bdb-xml
  databases/py-bdb-xml
  
The failure of "textproc/xmltooling" further breaks:

  security/opensaml
  www/shibboleth-sp
  
>How-To-Repeat:
Using pkgsrc-2017Q3 (and probably HEAD leading into pkgsrc-2017Q4),
attempt to build any of:

  games/enigma
  devel/xsd
  textproc/xqilla
  textproc/xmltooling
>Fix:
Workaround:

The following patch allows "games/enigma" to build.  A similar hack
may also help "devel/xsd" and "textproc/xqilla".  Not sure what
"textproc/xmltooling" would need:
