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. */ #include int main (argc, argv) int argc; char **argv; { char *progname; char *prefix; progname = argv[0]; argc--, argv++; if (argc < 1) { fprintf (stderr, "Usage: %s PREFIX ARGS...\n\ Echo each ARG preceded by PREFIX and a space.\n", progname); exit (2); } prefix = argv[0]; argc--, argv++; for (; argc > 0; argc--, argv++) printf ("%s %s%c", prefix, argv[0], (argc > 1) ?
