22	Nginx 1.1.4 can't build on Debian hurd-i386	Cyril Lavier	somebody	"Hi.

For the Debian packaging purposes, I try to make Nginx working under the hurd-i386 kernel.

The error is the following.

{{{

}}}

Under hurd, there is no PATH_MAX variable defined in the limits.h kernel header, and in any other header.

In order to have this issue corrected, I decided to set the PATH_MAX at 4096 (which is the common value in most Linux based systems). And after this, the build is working fine.

I attached a patch which does the trick.

I would like this patch to be applied upstream, as it will benefit all distributions providing a hurd kernel.

I'm working on the last version (1.1.4), and it can be applied/adapted on any other serie (1.0.x and 0.8.x), as Nginx always failed to build under hurd-i386.
