  Bug#14862 undefined reference to `isinf' on SOLARIS - strings/strtod.c
   - Change the configure test looking for 'isinf' so the value returned from isinf is used. That avoids the call to isinf being optimized away. 

  configure.in@stripped, 2006-09-12 15:47:45+02:00, msvensson@shellback.(none) +1 -1
    Use the value returned from isinf so it's not optimized away by the compiler(i.e gcc 4.1)

# This is a BitKeeper patch.  What follows are the unified diffs for the
