Follow-up Comment #3, bug #61399 (project make): You are right, I am not using the build_w32.bat script because I am running the build on Linux.
I checked the sources of the latest mingw-w64, and there is no implementation of isatty(), there are only lots of references in the .def files, so you were right again. Since you mentioned that the provided implementation of isatty() is needed, I removed my patch; after re-examining the the error message, I could not identify multiple conflicting implementations of isatty(), so I concluded that the same definition is presented to the linker via multiple paths; I added -Wl,--allow-multiple-definition and the linker no longer complained. As for the build, I used GCC 11.2 with mingw-w64 9.0.0 / UCRT; in a common Linux cross-build scenario: git clone https://git.savannah.gnu.org/git/make.git cd make git checkout -qf f8f9d371ff58a7195ca4abc9413f435c2bf2b998 bootstrap bash configure --prefix=.../win32-x64/install/windows-build-tools --build=x86_64-pc-linux-gnu --host=x86_64-w64-mingw32 --target=x86_64-w64-mingw32 --without-guile --without-libintl-prefix --without-libiconv-prefix ac_cv_dos_paths=yes make -j make install-strip The output of the verbose link command is: x86_64-w64-mingw32-gcc -C -Wall -Wextra -Werror -Wwrite-strings -Wshadow -Wdeclaration-after-statement -Wbad-function-cast -Wformat-security -Wtype-limits -Wunused-but-set-parameter -Wlogical-op -Wpointer-arith -Wignored-qualifiers -Wformat-signedness -Wduplicated-cond -ffunction-sections -fdata-sections -pipe -m64 -O2 -w -mthreads -std=gnu99 -O2 -v -Wl,--gc-sections -mthreads -std=gnu99 -Wl,--allow-multiple-definition -o make.exe src/ar.o src/arscan.o src/commands.o src/default.o src/dir.o src/expand.o src/file.o src/function.o src/getopt.o src/getopt1.o src/guile.o src/hash.o src/implicit.o src/job.o src/load.o src/loadapi.o src/main.o src/misc.o src/output.o src/read.o src/remake.o src/rule.o src/signame.o src/strcache.o src/variable.o src/version.o src/vpath.o src/w32/pathstuff.o src/w32/w32os.o src/w32/compat/dirent.o src/w32/compat/posixfcn.o src/w32/subproc/misc.o src/w32/subproc/sub_proc.o src/w32/subproc/w32err.o src/remote-stub.o lib/libgnu.a Using built-in specs.
