in order to compile iuser library you'll need to compile: 
log.c, error.c and iuser.c.

terror.c will do some tests using the win32 API.
terror.exe is a win32 binary that expects a valid filename as argument 
and it will complain if this will not be the case (without explaining why)

maketest.bat is for lcc-win32
makefile will build iuser for an unspecified  Un*x system.
