If that's Guile 1.8, get version 2.x.  There were lots of fixes in
2.0.x specifically for MS-Windows, so I wouldn't expect 1.8 to work
well on Windows.

FWIW, getuid works fine here in Guile 2.0.11 compiled for Windows.

I think system and system* both had "issues" before Guile 2.0.12, so
once again, I suggest to upgrade.
