## Regardless what has been configured, a user should always
## be able to  override  without  the need to reconfigure or
## change this file. Therefore we check variable $LDFLAGS.
## In almost all cases the precomputed flags are just ok but
## some  additional  flags are needed. To support this in an
## easy way, we check for the very first value. If this val-
## ue is
## '+'  -> append content of LDFLAGS to precomputed flags
## '-'  -> prepend content    -*-
## '='  -> do not use precomputed flags
## If none of these characters are given, the behaviour will
## be the same as if "=" would have been given.
