Error-messages when compiling bind 9.3.2

[Tom Schmitt]

Hi,

I'm not good in C-coding so I'm not sure if it matters, but when I'm
compiling BIND 9.3.2 on Solaris 10 with gcc 3.3.2, then I get (when I'm
running make) not only much warnings, but also some error-messages:

<SNIP>
gcc  -I/dns/src/bind-9.3.2 -I./include -I./../include
-I/dns/src/bind-9.3.2/lib/dns/include -I../../../lib/dns/include

-I../../../lib/isc/pthreads/include  -D_REENTRANT  -D_XPG4_2
-D__EXTENSIONS__ -g -O2  -W -Wall -Wmissing-prototypes -Wcast-qual
-Wwrite-strings -Wformat  -c os.c

os.c:401: error: `STDOUT_FILENO' undeclared (first use in this function)
os.c:402: error: `STDERR_FILENO' undeclared (first use in this function)
</SNIP>

Should I worry about these Error-messages or are these just for
beautification of the code?

Tom.
