* doc/doc.am: Rationalize Texinfo document installation targets. (install-txt-local) (install-info-local) (install-dvi-local) (install-pdf-local) (install-html-local): Name as prerequisites (only) the macros conditionally populated when `HAVE_MAKEINFO` and `USE_TEX` are defined. Thus we (re)build each document only if we can actually do so. If not, the user gets the "stock" version from distribution archive. --- ChangeLog | 13 +++++++++++++ doc/doc.am | 15 ++++++++++----- 2 files changed, 23 insertions(+), 5 deletions(-)
