Watcom 10.6, MASM 5.10 and TASM 3.1 are required to build

1. Build helix32, qtools and build (i.e. cd helix32 and then wmake)
2. Build blood (i.e. cd blood and then wmake)

Note: The Build Engine (by Ken Silverman) code has been effortlessly recreated by the gamesrc-ver-recreation project, and compiles close enough that DOSBlood can playback 11 hours of demo files without desyncronizing. If you prefer to use the original objects file, run clean.bat and then origlib.bat in the build directory
