Building with ghc prints beautifully formatted error messages on powershell (as in other terminals):
PS > ghc .\src\XXX.hs -package ghc -package ghc-paths -package filepath
[1 of 1] Compiling XXX ( src\XXX.hs, src\XXX.o )
src\XXX.hs:340:9: error:
parse error on input `<-'
Perhaps this statement should be within a 'do' block?

340 | blah <- blah blah blah

But when building through stack, something goes wrong:
PS > stack build
XXX-0.1.0.0: build (lib + exe)
Preprocessing library for XXX-0.1.0.0..

Is this a bug in stack, or is there a setting to fix it?
Thanks!
