Hi Wayne,

You might want to check -lmoldname90 is included and correct. Looking at
moldname.def.in in the mingwrt (technically the mingw-org-wsl now!) sources
includes a definition to write.

I was only looking as I don't know what -lmoldname has to do with this
problem, but it is a required component of linking - it appears to contain
the original crt functions.

Best Regards, Brian.

Best Regards, Brian.
