title: How to transform 32 bit *.lib files to 64 bit *.a files
body: <p>I am currently porting a 32 bit c++ program (with C++ Builder) to 64 bit Code. The application is linking a 3rd party dll and the 32-bit compiler project contains the associated lib file, as usual.
  In 64 bit mode, these &quot;.lib&quot; files need to be transformed into archives with extension &quot;.a&quot;. I know there is a conversion tool for that (a simple executable) I have used once successfully a while ago. But I cannot remember the name of that tool. Can someone help me here?</p>
