[webkit-dev] JavaScriptCore in Windows Applications

Hi Brent and all,

Oh my goodness, it compiled!  Thanks so much for all your help.

There is still an issue, however.  The point of my application is to  
generate JavaScript applications.  These applications do not  
necessarily use WebKit (they could, however) but they all use  
JavaScriptCore because they are written in JavaScript (and interact  
with objects vended by the application).  That means that I have to  
include WebKit (or at least JavaScriptCore) in all the generated  
applications.  But, the WebKit built by the Cairo port has a ton of  
DLLs that would have to be copied into each built application  
directory.  I'd much rather that only one DLL was copied. So my  
question is, is it possible to either merge DLLS or to compile all the  
source into one DLL in the first place?

Thank you ****very**** much,
