hdf5/bin/ltconfig
Bill Wendling b8f8c8cb90 [svn-r2507] Updated to most recent release of libtools (1.3.5). Most of the changes 
applied for various platforms which weren't supported by libtools are now
standard for libtools it seems. There were only a few of the previous
fixes I rolled forward (the diffs follow):

Usage: $progname [OPTION]... [HOST [LTMAIN]]
Generate a system-specific libtool script.
--debug enable verbose shell tracing
--disable-shared do not build shared libraries
--disable-static do not build static libraries
--disable-fast-install do not optimize for fast installation
--enable-dlopen enable dlopen support
--enable-win32-dll enable building dlls on win32 hosts
--help display this help and exit
--no-verify do not verify that HOST is a valid host type
-o, --output=FILE specify the output file [default=$default_ofile]
--quiet same as \`--silent'
--silent do not print informational messages
--srcdir=DIR find \`config.guess' in DIR
--version output version information and exit
--with-gcc assume that the GNU C compiler will be used
--with-gnu-ld assume that the C compiler uses the GNU linker
--disable-lock disable file locking
--cache-file=FILE configure cache file
LTMAIN is the \`ltmain.sh' shell script fragment or \`ltmain.c' program
that provides basic libtool functionality.
HOST is the canonical host system name [default=guessed].
