X-Git-Tag: v3.0.0~149
X-Git-Url: http://mj.ucw.cz/gitweb/?a=commitdiff_plain;h=80459c650b9739e06a8662e395a27ac481e2de3a;p=pciutils.git

Added support for GNU Hurd

2003-12-26  Marco Gerards  <metgerards@student.han.nl>

        Added support for the GNU Hurd (cleaned up by Martin Mares):

        * lib/configure [GNU]: Use the i386 ports for configuration access.
        * lib/i386-ports.c: Don't call iopl() on the Hurd.
        * lib/pci.h [OS_GNU]: Include <sys/types.h> and use it for defining
        u8 to u32.
