Re: dll compile, can not resolve with -module libs

[Guido Draheim]

okay, forget about that, I did resolve a few other problems
during libtool sequencing, and finally the "ld" does not
accept the module.dll as the cross-gcc's ld does also add
a "lib" at each "-l$name".. and can not find the module.dll

Now I have to rethink a few bits, like renaming the build-libs
apropriatly. It is interesting that we break windows'
name-conventions for libraries, happily adding "lib" before
the basename - am I right that this has changed from 
former tools targetting windows?

okay, need some sleep now, bye, guido
