[boost] bug report for bjam 3.1.11

Hi All,

I apologize if this has been reported before, but I couldn't find it 
after a long search. I encountered problems building bjam on a standard 
Linux distribution (uname -a: Linux 2.4.21-32.0.1.EL #1 Wed May 25 
14:34:59 EDT 2005 i686 i686 i386 GNU/Linux) with gcc. (same problem with 
  gcc 3.2.2 or 4.0.1). The executable seg faulted every time. I tracked 
it to the function var_defines() in variable.c which had a logic error 
at lines 124-130. I didn't investigate far enough to determine why the 
function was receiving strings consisting of a single quote, and I do 
not know if this is irregular or not, but in any case the attached patch 
  (output from diff -c) corrects the issue.

-Lewis
