Missing in 1.5.x:


compilations fails on (Debian) GNU/Hurd. There is 2 problems :

- PATH_MAX is not defined (PATH_MAX "seems to not be POSIX", that's why it's not present on Hurd)

- UIO_MAXIOV nor IOV_MAX are not defined, but writev is defined (workaround is to define a value for UIO_MAXIOV)

and :

- GNU/hurd defines sendfile() with the same signature as on Linux, maybe it can be used too.

here is a patch which make lighttpd work on GNU/Hurd:

Ok, i agree lighty shouldn't rely on PATH_MAX.

But the posix manpage for writev is pretty clear: http://www.opengroup.org/onlinepubs/007908775/xsh/write.html - IOV_MAX should be defined by limits.h (where it is listed as an extensions, ok; but i think writev depends on this extension)
