The routines seem to be sufficient. According to the ltdl documentation 
lt_dlinit may be called multiple times. The library is released if lt_dlexit is 
called as many times as lt_dlinit. This is what You are doing.

Hopefully the Windows version will be included in 4.28.

For loading the libraries that is fine and will save resources, when the 
libraries are not needed.

The libraries should not be unloaded before mpl_terminate. Hence  some function 
is needed to unload the libraries when GLPSOL is terminating.

Currently I am using the MPL structure to store which library has been 
successfully loaded. I guess it would not be thread safe to put the information 
into a static variable in glpsql.c.

I am ready to test as soon as You can provide a prerelease.

Best regards

Xypron
