+ *
+ * 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.
