Problem compiling latest gnulib on Solaris 9 i386 with Sun Studio

[Dagobert Michelsen]

Hi,

I just tried to build a static gnulib as described in
  
http://www.gnu.org/software/gnulib/manual/html_node/POSIX-Substitutes-Library.html#POSIX-Substitutes-Library
on Solaris 9 i386 with Sun Studio 12 and got the following error:

source='openat.c' object='openat.o' libtool=no \
DEPDIR=.deps depmode=none /bin/bash ../build-aux/depcomp \
/opt/SUNWspro/bin/cc -DHAVE_CONFIG_H -I. -I..  -DGNULIB_STRICT_CHECKING=1 
-I/opt/csw/include -D_REENTRANT  -xO3 -m32 -xarch=386 -c -o openat.o openat.c
"openat.c", line 99: undefined symbol: errno
"openat.c", line 99: undefined symbol: EISDIR
"openat.c", line 131: undefined symbol: errno
"openat.c", line 131: undefined symbol: ENOTDIR
cc: acomp failed for openat.c
gmake[4]: *** [openat.o] Error 2

Adding
  #include <errno.h>
to openat.c resolves the issue for me.



Best regards
