As far I understand purpose of this DllMain is to be able to create
glpk dll (instead of a static library) on MS Windows. Function export
definitions are in file w32/glpk_4_27.def (in glpk tarball). I have
not tried using this yet, usually build static lib.

I hope you are not suggesting to load MySQL and ODBC dlls in function
DllMain. From what I understand from :
http://msdn2.microsoft.com/en-us/library/ms682583(VS.85).aspx

"The entry-point function should perform only simple initialization or
termination tasks. It must not call the LoadLibrary or LoadLibraryEx
function (or a function that calls these functions), because this may
create dependency loops in the DLL load order"

Maybe MySQL and ODBC dlls should be loaded in some separate function.
