Comment:
The executable extensions are given by the environment variable %PATHEXT%.
On Vista:
PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC
I'm not entirely convinced GHC is doing the right thing here though. I
think there are two entirely separate cases which are being treated
equivalently:
1) Not specifying -o. ghc --make <name>.hs should create "<name>.exe".
Even ghc --make Main.exe.hs should create Main.exe.exe. This fixes this
bug in a clean way, without knowledge of which extensions are executable.
2) Specifying -o. ghc -o <name> should create <name>.exe unless name
already has an extension. i.e. -o foo.123 produces foo.123, but -o foo
produces foo.exe. This maintains existing behaviour.
I suspect this is being implemented as ghc --make <name>.hs is translated
to ghc --make <name>.hs -o <name>, which is merging the behaviour of the
two cases, and getting the first case (in this bug) wrong.
