Here's the unfinished and untested port to QNX of the stdio extension
modules. Since it's likely to be a better starting point for whomever
volunteers to support that platform than no port at all, I'm committing it.
2007-10-03 Bruno Haible <[EMAIL PROTECTED]>
Port the stdio extensions to QNX (untested).
* lib/fseterr.c (fseterr): Add support for QNX.
* lib/fbufmode.c (fbufmode): Likewise.
* lib/freadable.c (freadable): Likewise.
* lib/fwritable.c (fwritable): Likewise.
* lib/freading.c (freading): Likewise.
* lib/fwriting.c (fwriting): Likewise.
* lib/freadahead.c (freadahed): Likewise.
* lib/fpurge.c (fpurge): Likewise.
* lib/fseeko.c (rpl_fseeko): Likewise.
