Re: safer way to use gnulib

[Tatsuro MATSUOKA]

Hello 

I have written in previously
http://www-old.cae.wisc.edu/pipermail/octave-maintainers/2010-March/015519.html

The compiling of c++ source that includes gnulib source suffered from unfined 
errors even on the
quit.cc in libcruft.

I am using '--disable-docs' in the configure because I do not have latex system 
on Native windows. 
I have a flex but do not have lex library. Does it affect this matter?
