Compiling with OpenBSD's gcc-4.2.1 produces 2 warnings when compiling posixunix.c

[Christian Kellermann]

The line numers differ from building the latest dev snapshot and master but the source code line is the same:

posixunix.c:9214: warning: array size (4) smaller than bound length (1024)

The line in question contains:

t3=C_curdir(t2);

The second warning is generated for the line:

 t2= C_do_readlink(t1,((C_word*)t0)[2]);

Compiling with a newer gcc (4.8.2) from ports does not show these, so this might be a compiler optimisation bug in gcc or a bogus warning.

Compiling with -O0 still produced the warnings.

This has been observed on a 32-bit i386 Openbsd 5.5-current machine.

This seems to be due to #778. For some reason gcc doesn't define the standard that's being used (perhaps we should add --std=c99 just in case? But then it would break on platforms that have an older gcc)
