Dne 18.9.2015 v 19:02 Riccardo Mottola napsal(a):

I was getting a lot of "weak" unsupported while compiling on windows. At first, I thought it was a compiler thing (still using gcc 3.something) but it is not, it should be supported already. However, I found out that it is supported only with ELF targets and to my knowledge mingw has COFF. Thus it won't work anyway.

I propose this patch, may I commit it?
It makes at least go away the nasty warnings I was getting for any file. I suppose it wouldn't have worked anyway.

as long as things still compile for you, it should be OK.
