22/* Jim Blandy <jimb@occs.cs.oberlin.edu> - September 1992
23
24   When using GCC 2 as the linker in the build process, options
25   intended for the linker need to be prefixed with the "-Xlinker"
26   option.  If an option takes an argument, we need to use -Xlinker
27   twice - once for the option and once for its argument.  For
28   example, to run the linker with the options "-Bstatic" "-e"
29   "_start", you'd need to pass the following options to GCC:
30
31   -Xlinker -Bstatic -Xlinker -e -Xlinker _start.
32
33   The Emacs makefile used to use a Bourne Shell `for' loop to prefix
34   each linker option with "-Xlinker", but 1) the for loop was hairier
35   than one might hope because it had to work when there were no
36   arguments to pass to the linker - the shell barfs on a loop like
37   this:
38
39       for arg in ; do echo -Xlinker "$arg"; done
40
41   and 2) the whole compilation command containing this loop seems to
42   exit with a non-zero status and halt the build under Ultrix.
43
44   If I can't write a completely portable program to do this in C,
45   I'm quitting and taking up gardening.  */
