Package: libc6-dev
Version: 2.3.5-8
Severity: normal

One cannot use the swab function without producing a warning. Indeed
unistd.h defines it within a __USE_XOPEN ifdef, whereas this should 
not be needed according to:

http://www.opengroup.org/onlinepubs/009695399/functions/swab.html

But then if one do:
#define __USE_XOPEN
#include <unistd.h>

one get:
/usr/include/sys/wait.h:115: error: syntax error before '__stat_loc'
/usr/include/sys/wait.h:168: error: syntax error before '__stat_loc'
/usr/include/sys/wait.h:178: error: syntax error before '__WAIT_STATUS'

I don't know if this page has changed or not, but the fact is that swab
is now defined as an XSI extension. It is then normal that this function
is defined between __USE_XOPEN ifdef.

Those problems are gone. I am therefore closing the bug.
