Inno Setup: Conditional FLAGS

Question

I have a question about the FLAGS for a SOURCE and how i can make a FLAG dependent on a checkbox value.

In my case i have a DLL, thats can copied to the GAC oder to the app-folder.

Source: "some.dll"; DestDir: "{app}\lib"; Flags: ignoreversion, gacinstall; Components: main

How can i make the "gacinstall"-flag more flexible. I hope its a better way then duplicate the SOURCE line and set two conditions, like this:

Source: "some.dll"; DestDir: "{app}\lib"; Flags: ignoreversion; Check: not GACcondition;
Source: "some.dll"; DestDir: "{app}\lib"; Flags: ignoreversion, gacinstall, deleteafterinstall; Check: GACcondition;

There's no way to conditionally specify Flags parameter values e.g. by having a script function. My guess is that it's simply because many of those flags needs to be known already at compilation time. So your script is the best you can write for conditional Flags specification.
