Subject: * Makefile.am (EXTRA_DIST_M4): add prog_{lex,yacc}.m4 to distro.
X-Git-Tag: before-clocktime-fixes~5
X-Git-Url: https://git.fsl.cs.stonybrook.edu/?a=commitdiff_plain;h=b78070ce91655d9043ac99c9c49ca8889da1b365;p=am-utils-6.1.git

* Makefile.am (EXTRA_DIST_M4): add prog_{lex,yacc}.m4 to distro.

* configure.in: use new macros AMU_PROG_YACC and AMU_PROG_LEX.

* m4/macros/prog_yacc.m4: new macro to check if bison/yacc/byacc
exist, but exist with an error if none found.

* m4/macros/prog_lex.m4: new macro to check if f/lex exist, but
exit with an error if not found (am-utils requires f/lex).
