The '(C)' part is not an argument to the function. It's part of the
function name. By convention, such a function name is used to indicate the
implementation of an autoconf macro for a particular _AC_LANG value.

​So how does one supply an argument? Is it

gl_UNKNOWN_WARNINGS_ARE_ERRORS(C)([variable])?​
