Re: mingw-w64's libuuid.a : *** Warning: linker path does not have real file for library -luuid.

[Vincent Torri]

another solution is to just kill the stupid .la file. There is
absolutely NO reason to add to the linker static libraries that are
ONLY used in my Evil library and that are not used elsewhere.

I think that it is the best solution

thank you
