Writing to stdout should be supported by xfopen in the same way as it
supports, for example, .gz files, i.e. something like this:
fp = xfopen("/dev/stdout", "w");
where "/dev/stdout" is a special filename recognized within xfopen
(may be using "-" would be even better). This would allow writing to
stdout everywhere the filename is specified (for example, in glpsol).
However, this feature is not implemented yet, though it is quite easy
to implement it.
