This file contains information that is captured from running the configure
script.  Lines that begin with a "+" are command lines echoed by the
shell.  Other lines are the output of commands; usually the contents of
test case files or the output from compilers.  If configure does the
wrong thing, you can use the information captured here to aid in debugging.
