This happens when the location of gcc is under a path with non-ASCII directory in it:
{{{ PS C:\Users\日\stack-test> & 'C:\Users\日 \AppData\Local\Programs\stack\x86_64-windows\ghc-8.0.2\bin\ghc.exe' -no- user-package-db .\Main.hs [1 of 1] Compiling Main ( Main.hs, Main.o )
<no location info>: error: Warning: Couldn't figure out C compiler information! Make sure you're using GNU gcc, or clang Unable to start C:\Users\?\AppData\Local\Programs\stack\x86_64-windows\ghc-8.0.2\mingw\bin/realgcc.exe (error code: 123) `gcc.exe' failed in phase `Assembler'. (Exit code: 1) }}}
Tested with ghc 8.0.2 on Windows Server 2016 (same setup as in #15021).
