Newer automake versions have the dist target depend on BUILT_SOURCES
so that variable should not heavy build dependencies. This fixes the
dist target sufficiently, for CI purposes at least, in that it leads
to inclusion of the same list of files. Note that CI does not build
anything in the japi/ directory.
Several variables are considered "user variables" by the GNU Standards.
This means that the user can pass these to their ./configure and make
invocations as they see fit. These variables include CPPFLAGS, CFLAGS
and LDFLAGS.
This changeset pushes our use of these variables to the automake shadow
variables, AM_CPPFLAGS, AM_CFLAGS and AM_LDFLAGS, so that user variables
will no longer clobber flags required in order to build.
The AC_SUBST and PKG_CHECK_MODULE invocations in configure.ac as well as
acinclude.m4 are sufficient to trigger automake to insert initialization
logic for the variables these introduce. There is no need to do this by
hand. Wherever these values are needed, it is better to use a variable.
This allows for one-off overrides on the make command-line (without the
need to run ./configure) for one thing.
also add V_REV.
* backend/Makefile.am: Use variables to add libraries to backends
instead of direct substitution. Easier to touch up variables on
problem platforms then substitution. Also, add back in creating
dll.d directory; missed during conversion.
* backend/genesys_gl841.c: Portablity fixes for strict
C compilers.
