Subject: * automake.in (scan_one_autoconf_file): Declare
X-Git-Tag: Release-1-6~9
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=37c22b0520ed5bc7544e728db719888d5c02a722;p=automake.git

* automake.in (scan_one_autoconf_file): Declare
LEX_OUTPUT_ROOT and LEXLIB as configure variables when
AM_PROG_LEX or AC_PROG_LEX are seen.  This allows to ...
* lib/am/lex.am: ... remove the LEX_OUTPUT_ROOT and LEXLIB
definitions.  Search %SOURCE% in $(srcdir).  Use s||| instead
of s/// in the sed invocation, to support filenames containing
slashes.
* lib/am/yacc.am: Search %SOURCE% in $(srcdir).  Use s||| too.
* tests/lex5.test, tests/yacc8.test: New files.
* tests/Makefile.am (TESTS): Add them.

 * aclocal and automake are also installed with the version number

   This lets you have multiple versions installed simultaneously.
