-+ * This is a crude wrapper to use uClibc with gcc.
-+ * It was originally written to work around ./configure for ext2fs-utils.
-+ * It certainly can be improved, but it works for me in the normal cases.
-+ *
-+ * April 7, 2001
-+ *
-+ * A bug was fixed in building the gcc command line when dynamic linking.
-+ * The functions dlopen, etc. now work. At this time, you must make sure
-+ * the correct libdl.so is included however. It is safest to, for example,
-+ * add /lib/libdl.so.1 if using ld-linux.so.1 rather than adding -ldl to the
-+ * command line.
-+ *
-+ * Note: This is only a problem if devel and target archs are the same. To
-+ * avoid the problem, you can use a customized dynamic linker.
-+ *
-+ *
-+ * April 18, 2001
-+ *
-+ * The wrapper now works with either installed and uninstalled uClibc versions.
-+ * If you want to use the uninstalled header files and libs, either include
-+ * the string "build" in the invocation name such as
-+ * 'ln -s <ARCH>-uclibc-gcc <ARCH>-uclibc-gcc-build'
-+ * or include it in the environment variable setting of UCLIBC_ENV.
-+ * Note: This automatically enables the "rpath" behavior described below.
-+ *
-+ * The wrapper will now pass the location of the uClibc shared libs used to
-+ * the linker with the "-rpath" option if the invocation name includes the
-+ * string "rpath" or if the environment variable UCLIBC_ENV include it (as
-+ * with "build" above). This is primarily intended to be used on devel
-+ * platforms of the same arch as the target. A good place to use this feature
-+ * would be in the uClibc/test directory.
-+ *
-+ * The wrapper now displays the command line passed to gcc when '-v' is used.
-+ *
-+ * May 31, 2001
-+ *
-+ * "rpath" and "build" behavior are now decoupled. You can of course get
-+ * the old "build" behavior by setting UCLIBC_ENV="rpath-build". Order
-+ * isn't important here, as only the substrings are searched for.
-+ *
-+ * Added environment variable check for UCLIBC_GCC_DLOPT to let user specify
-+ * an alternative dynamic linker at runtime without using command line args.
-+ * Since this wouldn't commonly be used, I made it easy on myself. You have
-+ * to match the option you would have passed to the gcc wrapper. As an
-+ * example,
-+ *
-+ * export UCLIBC_GCC_DLOPT="-Wl,--dynamic-linker,/lib/ld-alt-linker.so.3"
-+ *
-+ * This is really only useful if target arch == devel arch and DEVEL_PREFIX
-+ * isn't empty. It involves a recompile, but you can at least test apps
-+ * on your devel system if combined with the "rpath" behavor if by using
-+ * LD_LIBRARY_PATH, etc.
-+ *
-+ * Also added check for "-Wl,--dynamic-linker" on the command line. The
-+ * use default dynamic linker or the envirnment-specified dynamic linker
-+ * is disabled in that case.
-+ *
-+ * Added options --uclibc-use-build-dir and --uclibc-use-rpath so that those
-+ * behaviors can be invoked from the command line.
-+ *
