This is a patch agains the original sources as released by
idsoftware. It gives you a source code ready for compile&run on
dec osf alpha (3.2G, but 4.0x should be ok too) If you want
to use the execuatable (alphadoom.gz), you may encounter the 
follwing problems:
- libmme.so not found: install the MMS runtime
- libmme.so version mismatch (loader message): do 
  a setenv _RLD_ARGS -ignore_all_versions (This may happen
  if you run the image on a osf 4.0x system

Changes made for dec alpha, second version
- Sound now available via dec's mme extension api:
  - SNDSERV no longer defined for OSF
  - soundsupport gets included, if OSFMME is defined. (Default
    in Makefile.alpha) most of the changes are in i_sound.c
Changes made for dec alpha, first version:
- all allocations (using Z_Malloc) have now a sizeof (bla) where
  needed
- pointer to numeric casts have been changed from cast to 
  int to cast to P2NUM
- OSF has values.h, but does not define MININT and MINLONG, defined them
  in doomtype.h
- ioctl not defined when using gcc, inserted in i_net.c and i_sound.c
- includes of linux/soundcard protected everywhere with #ifdef LINUX
- sys/filio.h not available in OSF
- usleep not defined in OSF-headers, definition in i_system.c inserted
- some XShm... routines not defined in headers, inserted in i_video.c
- errnos.h not available in OSF, protected with ifndef OSF in i_video.c
- multiply=1 changed to multiply=3 (otherwise microscope required to play)
- gcc wants pointers printed with %lx instead of %x (i_video.c)
- m_bbox.c needs doomtype.h included for MININT
- ifdef __BIG_ENDIAN__ changed to ifndef __BIG_ENDIAN__ in m_swap.c
  (Not required for the patch to work, but, Hmm, this way it's consistent 
   with the definitions in m_swap.h, and it works. However, I think the 
   name should be __LITTLE_ENDIAN__ ??? (confused, the alpha is big-endian 
   isn't it???))
- changed obsolete columndirectory-element from type void** to int
  (this struct is read from file, so the void* hurts on the alpha)
- ifndef SNDSRV changed to ifndef SNDSERV in s_sound.c
- casted alloca to the lhs type where needed
Note1: the changes should be compatible to linux, however, I did not test it
       because I currently dont have a linux box
Note2: The source code compiles and runs with gcc (version 2.7.2) and
       dec cxx (version V5.4-006). It does NOT run when compiled with 
       the dec cc. Both versions were built on an dec alpha running osf 3.2G
Note3: No sound-card in my alpha, so I think sound does not work...
       (second version: meanwhile looked at backpanel and found the soundcard,
        so soundsupport is available now)
Note4: Apply the patch the following way:
       gzip -d alphadoom.patch
       cat linuxdoom-1.10.src.tgz|gzip -dc|tar xvf -
       patch -p0<alphadoom.patch
       cd linuxdoom-1.10
       mkdir alpha
       gnumake -f Makefile.alpha
       (for the linuxdoom-1.10.src.gz, look at
        ftp://ftp.idsoftware.com/idstuff/source/doomsrc.zip)
Note5: You need some wad-files to run doom. I used doom1.wad from the
       shareware-version of doom for windows, which works fine
       (look at ftp://ftp.idsoftware.com/idstuff/doom/doom19s.zip)
