Ok, I've removed it from tsearch and tsearch2. But I can't check it with new flex:
% /usr/local/bin/flex -8 -Ptsearch2_yy -o'parser.c' parser.l
m4: illegal option -- P
usage: m4 [-d flags] [-t name] [-gs] [-D name[=value]]...
[-U name]... [-I dirname]... file...
%uname -a
FreeBSD xor 5.1-RELEASE FreeBSD 5.1-RELEASE #3: Fri Jun 13 20:34:53 MSD 2003
So flex calls m4 which isn't gnu m4, it is system utility. GNU m4 is named as
gm4... I can't find any option about which m4 to use.
