OpenEuphoria

I'm trying to compile a program that otherwise works fine interpreted.

How do I fix this error?

Build directory: build-876376\ 
Translating code, pass: 1 2 3 4 5 6 7 8 9 10 11  generating 
Compiling with Watcom 
Compiling   0% init-.c 
Couldn't compile file 'init-.c' 
Status: -1 Command: wcc386  /dEWINDOWS /bt=nt /mf /w0 /zq /j /zp4 /fp5 /fpi87 /5 
r /otimra /s /IC:\euphoria init-.c 

This is on my Windows 8 PC, and I might not have compiled on it in the past, though I thought I did...
