args in that script to fix it. I figured since the SHA1 is checked anyways,
so it shouldn't matter. You'll probably not want to include this change
upstream though

You may have a too-old version of wget that doesn't support SHA256 certs.

winsock.h. Include winsock2.h instead" This is caused by the inclusion of
<windows.h> before <winsock2.h> because windows.h will include winsock.h
and it causes a conflict when ws2tcpip.h gets included. I had to move the
includes so that ws2tcpip.h gets included before windows.h is included.
I've attached a patch for that.

This is happening because you're using a newer win32api - there are lots of
reports of people having similar issues with various programs.
I'll commit the patch, thanks.

needed. I'm not sure if it was because my gcc was version 4.8.1 instead of
the 4.7.2 you suggest, but I just added the -static-libgcc option to the
LD_HARDENING_OPTIONS variable in libpurple/win32/global.mak and that fixed
it (probably a better idea though to add it to the DLL_LD_FLAGS in
global.mak and the LDFLAGS in Makefile.mingw instead of the

This is part of the reason I haven't upgraded the version of gcc I use.
There are a number of problems using "-static-libgcc" like that (it's fine
for a static standalone thing, but when you have multiple things that are
compiled with different gcc versions, you potentially will have runtime
Eventually we'll need to bite the bullet and depend on libgcc*, but I'm in
no hurry to do that because I don't see any value in upgrading at this time.
