First, a plug for free software: had you chosen to build your entire
application using MinGW, instead of using this outdated, proprietary,
non-free and restrictively licensed compiler suite, then you would
never have encountered...

...this error.

Ok.  This probably isn't the answer you hoped for, so here is the
authoritative answer I promised, when I responded to your earlier
post to MinGW-MSYS.

 int _get_output_format( void );

is a standard MSVC function, but it was not introduced until VS-2005;
therefore, there is no implementation provided by VC-6.0.  To support
users of more recent MSVC, (with MSVCRT version >= 8.00), who might
also wish to use the _set_output_format() feature, and who also wish
to use MinGW's enhanced printf() implementation, (which is what uses
pformat.o), a call to _get_output_format() is needed.  To satisfy
that requirement, when linking against earlier MSVCRT versions,
MinGW's own import libraries provide a stub implementation of this
function, which isn't provided by Microsoft's own libraries.  Thus,
you need to provide your own stub; add:

 int _get_output_format( void ){ return 0; }

as a global function definition, to the source which provides your
main() function, when you must use non-MinGW libraries, for linking
to MSVCRT versions predating msvcr80.dll.
