Summary:                    A clean svn checkout needs bison to compile but
configure does not check for it
Description: 
main/Makefile has a line to regenerate main/ast_expr2.c from the
main/ast_expr2.y
Normally this would only happen when the .c file is older then the .y
file.

While it might be so that both files have the same timestamp for the
Digium devs that do checkouts over LAN, this is not true for people with
normal DSL and/or Cable internet (and yes, there are even ppl with dialup
56kbps connections out there) and those checkouts will try to regenerate
the .c file.
We can fix this in three ways:
1) Add bison to the configure script
AC_PATH_PROG([BISON], [bison], [])
if test -z "$BISON"; then
 AC_MSG_ERROR([cannot find bison])
fi
2) rename the Makefile entry so it wont be run by default and people who
edited the .y file have a Makefiletarget to regen the .c file
3) Fix the core issue by renaming the .y file so it's checkedout before
the .c file.

Russell already said he did not want option 1 to go in because we 'do not
depend on bison'
