I experienced a failure in linking qmgr on Windows using VS2008 and MinGW gcc 6.2.0.
I ran .appveyor\appveyor_helper.bat to compile all PBS deps; this step succeded.
Then I built PBSPro:
Got unresolved references to all readline functions in linking qmgr.
I believe this is due to incompatibility between libedit_static.a built by gcc and VS2008.
