* Allow overwriting of conflicting packages being removed. (Bug#2614.) * a.out control file says Pre-Depends: libc4 | libc. (Bug#2640.) * ELF control file and libc dependencies changed to use finalised scheme. * ELF control file and libc dependencies for i386 only. (Bug#2617.) * Guidelines say use only released libraries and compilers. * Install wishlist as /usr/doc/dpkg/WISHLIST. * Remove spurious entries for Guidelines in info dir file. * dpkg-deb --build checks permissions on control (DEBIAN) directory. * Spaces in control file fields not copied by dpkg-split. (Bug#2633.) * Spaces in split file part control data ignore. (Bug#2633.) * Portability fixes, including patch from Richard Kettlewell. * Fixed minor configure.in bug causing mangled GCC -W options. -- Ian Jackson <ian@chiark.chu.cam.ac.uk> Thu, 4 Apr 1996 01:58:40 +0100
