0.3.6 on both PCs: igneumd.exe (built on PC 1 with GCC 13's mingw) shipped with the Mac toolchain's GCC 16
libstdc++-6.dll, which no longer exports seven symbols the exe imports (std::codecvt_utf8_utf16 and a
stringbuf::seekpos); Windows refused the node with Entry Point Not Found. -C link-arg=-static had never removed
the libstdc++ import (0.3.5's Mac-built exe carries it too).
- packaging/windows/check-runtime-dlls.sh: objdump imports per DLL against the DLL's exports; shown to fail
the 0.3.6 pairing (7 missing) and pass 0.3.5's; run by push-inputs.sh before signing and by make-payload.sh
- push-inputs.sh: DLLs next to the exes first, then the Mac toolchain
- jobbuild.rs: the PC's windows stage copies its own toolchain's three DLLs into the pack (unit test);
build-job.mjs accepts the small DLL PE files and places them next to the exes
- cross-build.sh: -static-libstdc++ added as a try (measured on the 0.3.7 build)
- the six version files: 0.3.7
