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.
link-warning.h: $(top_srcdir)/build-aux/link-warning.h
