The LIBS variable is not mentioned in the output of "./configure --help",
nor is there any code in the "configure" script to note that it had a
environment value when the program started.  The script does make use
of any pre-existing value, prexfixing any new library it wants to test.

How's this for a better description...


The scripts generated by "autoconf" will make use of any existing LIBS
environment variable in much the same way as CFLAGS and LDFLAGS are used.
When doing tests for libraries, the lib being tested is prefixed to that
variable and the test made.

However, the value of the LIBS envionment variable is not saved in the
"config.status" file to be used again when "./config.status --recheck"
is run.  Thus, it is possible to have it configure correctly the first
time but not when it is re-checked.
