This is necessary for executing "make" in a VPATH build of a package that uses prefix-gnulib-mk and a module such as alloca-opt. * modules/alloca-opt (Makefile.am): Before generating the .h-t file, ensure that the directory in which we want to create it exists.

# The BUILT_SOURCES created by this Makefile snippet are not used via #include

# statements but through direct file reference. Therefore this snippet must be

# 'all' defined above.

# FIXME: The link-warning.h rule probably does not work if

# gnulib-tool's --gnu-make option is used, when the build is an
|
|
# out-of-source build that relies on VPATH.
