minix/drivers/dp8390/rtl8029.c
Arun Thomas 2a8fabf4ad Include directory reorg and makefile updates. 
-Convert the include directory over to using bsdmake
 syntax
-Update/add mkfiles
-Modify install(1) so that it can create symlinks
-Update makefiles to use new install(1) options
-Rename /usr/include/ibm to /usr/include/i386
-Create /usr/include/machine symlink to arch header files
-Move vm_i386.h to its new home in the /usr/include/i386
-Update source files to #include the header files at their
 new homes.
-Add new gnu-includes target for building GCC headers
