Seems reasonable enough.

FWIW, if the information was to be retained, fprintf() (or fputs())
would be the correct approach, although it should be a single call
rather than one per line.

Note that the C preprocessor concatenates adjacent string literals, so
large chunks of text can be split into lines like so:

	fprintf(stderr,
		"\n"
		"Version: GRASS5.0, update: October 1999\n"
		"\n"
[snip]
		"Please cite these references in publications where the results of this\n"
		"program are used.\n"
		"\n"
	);

without having to use a separate function call for each line.
