bug#9714: [PATCH] maint: remove vestigial de-ANSI-fication support

[Stefano Lattarini]

The support for automatic de-ANSI-fication has been deprecated in
automake 1.11.2, and will be removed altogether in automake 1.12.
Also, coreutils does not use the `ansi2knr' option since at least
2003-03-14 (commit b9fa45f2b01d0e395b7ddd845ebabb9528cf3f12 "remove
ansi2knr junk", and a few preceding commits).

* /m4/jm-macros.m4 (gl_CHECK_ALL_TYPES): Don't require
`AM_C_PROTOTYPES' anymore.  This is required to avoid a (mostly
spurious) warning from automake.
