Unresolved external symbol

[Chris Saunders]

I have sent this message to this list before.  There were some spelling and 
formatting errors and have corrected them.  I may have received no replies 
because the question is considered inappropriate for this list.  If that is 
the case I would appreciate someone letting me know.  Below is the corrected 
message.

I built the GMP 5.0.1 library using MSYS.  I am working on an Eiffel 
language interface to GMP.  My Eiffel compiler translates its code to C and 
then uses cl from the Microsoft Windows SDK v7.0 to compile that C code.

Here is an error I am getting from the C compilation:

2 C Compiler Error: Error LNK2019: unresolved external symbol
___mingw_vfprintf referenced in function _fprintf libgmp.aThe function I was 
attempting to wrap that is causing this error is mpf_out_str.

Now mpf_inp_str compiled successfully and so have all the other functions. 
When I built GMP I did do "make check" and all tests ran successfully.  I'm 
hoping someone might know the source of this error?
