gettext 0.10.37 unportable use of $< in doc/Makefile.am

[Paul Eggert]

POSIX says that the $< construct in makefiles can be used only in
inference rules and in the .DEFAULT rule; its meaning in ordinary
rules is unspecified.  gettext 0.10.37 assumes the GNU make semantics
in doc/Makefile.am, which causes behavior like this on Solaris 8:

        $ make gettext.html
        /opt/reb/bin/texi2html -expandinfo -number -monolithic 
        Need exactly one file to translate
        Try 'texi2html -help' for usage instructions.
        *** Error code 255
        make: Fatal error: Command failed for target `gettext.html'

Here is a patch.

2001-05-12  Paul Eggert  <address@hidden>

        * doc/Makefile.am (install-dvi, gettext.ps, install-ps,
        install-pdf, gettext.html, gettext_toc.html,
        install-html-monolithic):
        Do not assume that $< evaluates to the first dependency; this
        isn't true in SVR4 make (e.g. Solaris 8 /usr/ccs/bin/make).
