# compile410.sh -- per-TU compile verification for the 4.10 literal-source
# reconstruction, using the fleet's own Borland C++ 4.52 with the authentic
# OPT.MAK flags (CODE/BT/OPT.MAK = the BTL4OPT.EXE recipe).
#
# Usage:
#   ./compile410.sh <file.cpp> [more.cpp ...]   compile specific TUs
#   ./compile410.sh --sweep                     sweep all surviving originals
#
# Output .obj files land in the current directory.  -DNO_PRECOMPILED_HEADERS
# dodges the not-yet-reconstructed mech-family headers (BT.HPP gates on it);
# drop it once mech.hpp/btplayer.hpp/mechsub.hpp exist in 1995 form.
