There was no answer from the DragonFly BSD developers. So I'm adding the
DragonFly BSD support without their system support.
2008-04-26 Bruno Haible <address@hidden>
Add tentative support for DragonFly BSD.
* lib/stdio-impl.h: Add macros for DragonFly BSD.
* lib/fbufmode.c (fbufmode): Update conditionals. Use fp_ instead of
fp.
* lib/fflush.c (clear_ungetc_buffer, disable_seek_optimization,
restore_seek_optimization, update_fpos_cache, rpl_fflush: Likewise.
* lib/fpurge.c (fpurge): Likewise.
* lib/freadable.c (freaadable): Likewise.
* lib/freadahead.c (freadahead): Likewise.
* lib/freading.c (freading): Likewise.
* lib/freadptr.c (freadptr): Likewise.
* lib/freadseek.c (freadptrinc): Likewise.
* lib/fseeko.c (fseeko): Likewise.
* lib/fseterr.c (fseterr): Likewise.
* lib/fwritable.c (fwritable): Likewise.
* lib/fwriting.c (fwriting): Likewise.
