`bin/mhs Example -oEx` fails with missing md5 symbol
Building executables with mhs is failing for me because it is not including the md5.c source when compiling. I needed to make this change to get it to work:
diff --git a/src/MicroHs/Main.hs b/src/MicroHs/Main.hs
index e3ff1e4..6749392 100644
--- a/src/MicroHs/Main.hs
+++ b/src/MicroHs/Main.hs

If records are not supported, I think that would be worth mentioning in the README.
This is what I tried:
module Record (R(..)) where
data R = R1 { r1Field :: () }
The error is
mhs: "./Record.hs": line 3, col 13:
found: {
expected: LQIdent ( UQIdent [ literal :: => ! | deriving ; }

getRaw seems to be failing on Fedora Linux
I have only tried on Fedora Linux Rawhide so far, but this might affect other Linux distros too?
Maybe I should re-bootstrap?

This also leaves the terminal in a bad state (eg Backspace no longer works): reset helps a little.
