[llvm-commits] CVS: llvm/autoconf/acinclude.m4

[John Criswell]

Changes in directory llvm/autoconf:

acinclude.m4 updated: 1.1 -> 1.2

---
Log message:

The configure script now defines BISON as the name of the bison program and
YACC as bison -y.  In this way, we ensure that bison is being used, but
the Makefiles have macros for using bison itself and for getting bison to
act like it is traditional yacc.

Diffs of the changes:  (+5 -1)
