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:
"Version: GRASS5.0, update: October 1999\n"
"Please cite these references in publications where the results of this\n"
"program are used.\n"
without having to use a separate function call for each line.
