 Description:
 A C macro for emitting link time warnings.
 
+Applicability:
+all
+
 Files:
 build-aux/link-warning.h
 
 Depends-on:
 
 configure.ac:
+AC_REQUIRE([gl_FEATURES_H])
 
 Makefile.am:
+# The BUILT_SOURCES created by this Makefile snippet are not used via #include
+# statements but through direct file reference. Therefore this snippet must be
+# present in all Makefile.am that need it. This is ensured by the applicability
+# 'all' defined above.

 BUILT_SOURCES += link-warning.h
 # The link-warning.h that gets inserted into generated .h files is the same as
 # build-aux/link-warning.h, except that it has the copyright header cut off.
