A .a file usually refers to a library that you can link a program to. For
instance, if you program in c, you'd include the headers of the library, and
add the library to your linker libraries.
So the only way to use it is to make a progral in c that exports all the
functions.
Another problem is that the .a extension is used in Unix and Linux systems.
But GNU compilers for windows also use .a, so there is no way to tell if it
is a windows or Linux library. I'm not even 100% sure if it matters, but
normally compiled code is OS specific.
