24 # This script is designed to be used from a Makefile that uses libtool
25 # to build libraries as follows:
27 # LTLDFLAGS = $(shell libtool-ldflags $(LDFLAGS))
29 # Then, use (LTLDFLAGS) in place of $(LDFLAGS) in your link line.

41 # that begin with -f or with a double-dash. So, it will
42 # think these options are linker options, and prefix them
43 # with "-Wl,". Then, the compiler driver will ignore the
44 # options. So, we prefix these options with -Xcompiler to
45 # make clear to libtool that they are in fact compiler
46 # options. Similarly for e.g. -static-libstdc++, or
