Then + concurrent builds may fail: one make might be aiming one of its + jobs at compiling src/bison, and another job at generating the man + page. If the latter is faster than the former, then we have two + makes that concurrently try to compile src/bison. + + This might also be a more convincing explanation for the failure + described in the patch "build: fix paths". + + * Makefile.am (SUFFIXES): Initialize. + * build-aux/move-if-change: New, symlink to gnulib's. + * build-aux/local.mk: Ship it. + * doc/common.x: Remove, merged into... + * doc/bison.x: here. + * doc/local.mk (doc/bison.help): New. + ($(CROSS_OPTIONS_TEXI)): Depend on it. + Use src/bison. + (.x.1): Replace with... + (doc/bison.1): this explicit, simpler, target. + (common_dep): Remove, inlined where appropriate. + (SUFFIXES, PREPATH): Remove, unused. + +2009-08-12 Akim Demaille + + gnulib: improve prefixing. + * configure.ac (gl_PREFIXED_LIBOBJS): Don't rename it, rather, + change the value of... + (gl_LIBOBJS): this. + Adjust more variables. + * etc/prefix-gnulib-mk (prefix_assignment): Don't rename + gl_LIBOBJS. + (prefix): Also transform rules whose targets have slashes. + Use $prefix liberally. + Map @MKDIR_P@ to $(MKDIR_P). + Prefix directories that are mkdir'd. + +2009-08-12 Akim Demaille + + build: fix paths. + When using $(top_builddir) inconsistently, Make (including GNU + Make) is sometimes confused.
