Bug ID: 95253 Summary: [10/11 Regression] Build failure on MSys. Wrong dependency file escaping on Windows. Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: daniel.f.starke at freenet dot de Target Milestone: --- Previously in gcc 9.3.0, escaping of the dependency file output still worked well. Now I get a dependency check error from make when building mingw-w64 crt due to wrong output escaping in gcc 10.1.0. 9.3.0 output: E:/msys/mingw64/include/windows.h 10.1.0 output: E\:/msys/mingw64/include/windows.h Obviously, the column operator should not be escaped here. Compiled gcc in both cases on MSys/MinGW (not MSys2) with: Target: x86_64-w64-mingw32 Configured with: ../gcc-src/configure --enable-languages=c,c++ --enable-seh-exceptions --enable-threads=posix --disable-nls --enable-shared=libstdc++ --enable-static --enable-fully-dynamic-string --enable-lto --enable-plugins --enable-libgomp --with-dwarf2 --disable-win32-registry --enable-version-specific-runtime-libs --prefix=/mingw64 --with-sysroot=/mingw64 --target=x86_64-w64-mingw32 --enable-targets=all --enable-checking=release --with-gmp=/new-gcc/lib/gmp-6.1.2 --with-mpfr=/new-gcc/lib/mpfr-3.1.6 --with-mpc=/new-gcc/lib/mpc-1.1.0 --with-isl=/new-gcc/lib/isl-0.18 --with-host-libstdcxx='-lstdc++ -lsupc++' Thread model: posix Supported LTO compression algorithms: zlib
