Solaris 7, standard gcc 2.95.2 install, gnu make.
>Description:
"make all info" fails with:

lex -ofconfigl.c ./fconfigl.l
lex: illegal option -- o
Usage: lex [-ewctvnVY] [-Q(y/n)] [file]
*** Error code 1
make: Fatal error: Command failed for target `fconfigl.c'

The lex supplied with Solaris does not recognize the o option.

After installation of lex, make all info failed again with reference to 
yacc-related problems. Installing bison gave a successful build.
>How-To-Repeat:

>Fix:
Either specify in the documentation that GNU flex and bison are needed on 
certain systems or modify configure to take this into account.
