Comment (by thomie):

 Oh, Phyx on #ghc says `-pgmF` requires a `.bat` file. Sure enough, then it
 works:

 {{{
 $ echo 'cat %2 > %3' > preprocess.bat
 $ chmod +x preprocess.bat
 $ ghc -F -pgmF ./preprocess.bat hello.hs
 C:\msys64\tmp\test>cat "hello.hs"
 1>"C:\msys64\tmp\ghc1556_0\ghc1556_1.hspp"
 $ echo $?
 0
 }}}
