Yes. If you read the document at that URI, it tells you which headers
to #include, which libraries with which to link, and which DLLs are
required at run time. So...

1) Check that MinGW provides the required header(s), (in c:\mingw\include
for a standard installation).

2) Check that the symbols you need to reference are defined, and that
functions you wish to call are declared, in the appropriate MinGW header;
(some are incomplete, due to inadequate documentation from Microsoft).

3) Check that MinGW provides the requisite libraries; (where Microsoft say
to use foo.lib, you look for libfoo.a or libfoo.dll.a, in c:\mingw\lib).

4) Check that the *system* provides the requisite DLLs; (most often, you
will find them in c:\windows\system32).

If all four checks pass, you should be able to use that API, without recourse
to any other resource.

As an aside, isn't it true that current versions of the GNU linker can
link directly against the DLL, even if the import library libfoo.dll.a
is not available?

It is. You need to add the directory with .dll files to the linker path.
