Re: [Vala] Vala HEAD is broken on MacOSX

I just reported this in the irc few hours ago. The commit was in 10th of february. And jurg ha no plans to 
remove that claiming for optimization issues.

 So the idea would be to fix this on the affected platforms:

Osx, iphone and windows.

I have just appended the inline definition of strnlen into the system's string.h include file. This is just a 

Any idea? Any program compiled against glib-2.0.vapi will suffer the same issue.

The reason is that strnlen is not defined on macosx (at least on
10.6.4 + xcode 3). The easiest way is to implement it on this platform

size_t strnlen(const char *s, size_t n)
 const char *p = (const char *)memchr(s, 0, n);
 return(p ? p-s : n);
