+/* prefix-args.c - echo each argument, prefixed by a string.
+   Jim Blandy <[email protected]> - September 1992
+
+   When using GCC 2 as the linker in the build process, options
+   intended for the linker need to be prefixed with the "-Xlinker"
+   option.  If an option takes an argument, we need to use -Xlinker
+   twice - once for the option and once for its argument.  For
+   example, to run the linker with the options "-Bstatic" "-e"
+   "_start", you'd need to pass the following options to GCC:
+
+   -Xlinker -Bstatic -Xlinker -e -Xlinker _start.
+
+   The Emacs makefile used to use a Bourne Shell `for' loop to prefix
+   each linker option with "-Xlinker", but 1) the for loop was hairier
+   than one might hope because it had to work when there were no
+   arguments to pass to the linker - the shell barfs on a loop like
+   this:
+
+       for arg in ; do echo -Xlinker "$arg"; done
+
+   and 2) the whole compilation command containing this loop seems to
+   exit with a non-zero status and halt the build under Ultrix.
+
+   If I can't write a completely portable program to do this in C,
+   I'm quitting and taking up gardening.  */
