Message : compile: implement library search to support MSVC static linking * lib/compile (func_cl_wrapper): Implement library search and -static option so that the user can select whether to prefer dll import libraries or static libraries. This enables MSVC to link against dlls generated by libtool without requiring libtool or workarounds such as -lfoo.dll etc. Makes the tests/static.at test case in libtool pass. * tests/compile3.test: Don't trip up if there happens to exist a "foo" library in the library search path. * tests/compile6.test: New test, verifying the library search. * tests/Makefile.am (TESTS): Update.

Usage: compile [--help] [--version] PROGRAM [ARGS]

Wrapper for compilers which do not understand `-c -o'.
Remove `-o dest.o' from ARGS, run PROGRAM with the remaining
arguments, and rename the output as expected.

If you are trying to build a whole package this is not the
right script to run: please start by reading the file `INSTALL'.
