Re: error: invalid character `' (ASCII 0) near line 164, column 2 [changeset]

The error below has returned for me.

>From config.log, it appears that the proper flex was found.

configure:47631: checking for flex
configure:47647: found /sw/lib/flex/bin/flex

... and its version is > 2.5.30 ...

$ /sw/lib/flex/bin/flex --version
flex 2.5.35

At the top of lex.ll I see

  25 %option prefix = "octave_"
  26 
  27 %top {
  28 #ifdef HAVE_CONFIG_H
  29 #include <config.h>
  30 #endif
  31 }

If I reinstate the reverted changeset below ...

        http://hg.savannah.gnu.org/hgweb/octave/rev/e6441e13acb2

... then all works as expected. I realize that reinstating this change is not 
the proper fix. I did it to verify the context of the problem.

My last successful build occurred after the changeset below

        http://hg.savannah.gnu.org/hgweb/octave/rev/323c9cbbd02a

Does anyone have an idea of what changed that could produce this problem?
