Depending on the compiler and the flags, there is a chance the version
in /usr/local/include will be found first.  Using "pkg which
/usr/local/include/ansidecl.h", you might be able to find out which port
originally installed it.

More current versions of the gcc ports install this header into version-
specific directories, e.g.:

$ find /usr/local -type f -name ansidecl.h
=
/usr/local/lib/gcc48/gcc/i386-portbld-freebsd11.0/4.8.5/plugin/include/ans=
idecl.h
=
/usr/local/lib/gcc47/gcc/i386-portbld-freebsd11.0/4.7.4/plugin/include/ans=
idecl.h
=
/usr/local/lib/gcc49/gcc/i386-portbld-freebsd11.0/4.9.4/plugin/include/ans=
idecl.h
=
/usr/local/lib/gcc5/gcc/i386-portbld-freebsd11.0/5.3.0/plugin/include/ansi=
decl.h
=
/usr/local/lib/gcc6/gcc/i386-portbld-freebsd11.0/6.0.0/plugin/include/ansi=
decl.h

This makes it less likely to be picked up by accident.  If your
/usr/local/include/ansidecl.h file is not owned by any port, you might
as well delete it, or move it out of the way.
