/* prefix-args.c - echo each argument, prefixed by a string.
Jim Blandy <> - 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
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. */
