Sunos4-1-4 builds...

[David S. Miller]

Building the linker uses flex, however the configuration process does
not add '-lfl' to the list of libraries to link the final ld.new
binary with.  Is there a certain reason that -lfl is not added to the
set of libs to link with?

It shouldn't be necessary, at least not for modern versions of flex.
-lfl just defines main and yywrap.  main is defined in ldmain.c, and
yywrap is defined in ldlex.l.  Is it causing trouble?  What version of
flex are you using?

Currently flex 2.4.5 is installed on the machine which I do SunOS gas
testing..  Precisely, without adding -lfl the compilation fails with
undefined references to:

_yy_flex_realloc
_yy_flex_free
_yy_flex_alloc

This could be something stupid with the way I installed flex or the
fact that is an older version.

I don't have any copies of flex which are that old, so I don't know
what the problem is.

We are running flex 2.5.2.

Linking against -lfl will cause problems if people are not using lex
rather than flex, since in that case -lfl won't exist.  You can use a
different lexer by building with make LEX=lex.
