A new Linux job installs the andrewwutw DJGPP v3.4 cross-toolchain
(gcc 12.2.0, sha256-pinned), cross-compiles uc2.exe with
cmake/djgpp.cmake, and verifies the result is a DJGPP go32 DOS
executable. The DOS build had no CI coverage and could regress
silently.
The repo carried two diverged DJGPP toolchain files. djgpp.cmake
(referenced by the build docs) forces -nostdinc with explicit DJGPP
include paths, so it builds cleanly even on hosts where /usr/include
would otherwise leak past the cross-compiler. djgpp-toolchain.cmake
(previously referenced by the README) relied on the cross-gcc finding
its own headers and broke in that case. Keep djgpp.cmake as the single
toolchain file, point the README and roadmap at it, and drop
djgpp-toolchain.cmake.
