errors linking to library

[Mathew Yeates]

I have a library I created with MSVC's lib.exe after compiling some 
fortran objects with gfortran

lib.exe [fortran objects] /NODEFAULTLIB /OUT:mylib.lib libgfortran.a

When I try and link to this library with MSVC's link.exe after compiling 
c code with cl.exe I get
a warning message
link.exe [ cobjects] libmingw32.a libmingwex.a libgcc.a mylib.lib

mylib.lib(unix.o) : warning LNK4217: locally defined symbol __iob 
imported in function __gfortrani_flush_if_preconnected

Also, whenever an output statement is executed I get a fortran error.
"Fortran runtime error: End of record"

Any help?
