limitation of AC_REPLACE_FUNCS

[Werner LEMBERG]

Is there any reason why AC_REPLACE_FUNCS and related functions are
limited to C?  Wouldn't it be better to use the current value of
AC_LANG to determine the appended suffix?  Another possibility is to
add an additional optional argument to set the suffix.

In my case I have a library composed of C and C++ files (libgroff),
and I want to use a newly written mkstemp.cc if necessary.  Any chance
to do that with autoconf 2.50 which I actually use?
