Re: Please add code to pick up SOLIB_SEARCH_PATH env var.

[Pierre Muller <pierre.muller@ics-cnrs.unistra.fr>]

   I was wondering if your patch
would work if the environment variable had
several entries, like;
SOLIB_SEARCH_PATH=/myprefix/lib:/myprefix/lib64

   Does access return 0 if you
give it the whole evironment variable, or should
you test the coponents one by one?
