dnl Work around a suspected bug in libtool:
dnl
dnl Remove excessive trailing slash from search dir names in the libtool script.
dnl It occurs in dir names obtained by 'gcc -print-search-dirs' in the created
dnl configure script and causes a test on dir names in libtool to fail,
dnl leading to confusing (but harmless) 'warning: <lib> seems to be moved'.
dnl
dnl This should be fixed in the libtool package itself as all other dir names
dnl there have no trailing slash.
dnl ---------------------------------------------
dnl Work around problem due to LTCFLAGS:
dnl
dnl CFLAGS is passed to LTCFLAGS directly from configure instead of Makefiles.
dnl Fixing LTCFLAGS here will help compile xine-list on some crazy platforms.
dnl
dnl It disables multi-pass compilation of xine-list.
