Lets say I have an Ada package ABC. It uses openssl extensively. I use the GPL license for ABC, but add a clause expressly allowing it to be linked against openssl. Is this a problem? On one hand ABC and openssl should be OK, but on the other hand openssl and the GNAT runtime library are both linked in the one executable. Is this really a problem? Openssl is not derived from the GNAT run time library, it doesn't even use the GNAT run time library. As much as I like the GPL, I dislike the fact if it affects unrelated software that just happens to be used by the one package. -- Brian May
