Mingw GCC-generated boost_thread libraries do not have _win32 suffix in version 4.8.1

[qdii]

The current version of boost.m4 assumes that versions of boost_thread generated by Mingw are called boost_thread_win32. This is not true with Mingw GCC 4.8.1, which calls them libboost_thread. I am not sure when this change occurred though.

As a result, autoconf fails to detect them even though they are present.

Thanks, can you post a fix?

Yes, I will try to

this appears to affect 1.56 as well, i'm going to see if commenting out the suffix thing helps

[kotoroshinoto]

It does... so if we can determine which version of boost where this change occurred, it should be simple to if/then around the lines 974-976 to avoid this issue

[kotoroshinoto]

are we sure this was a mingw change as opposed to a change in the boost buildsystem?
