In the following thread on the `cygwin' mailing list (April 2009) Dave Korn explains some of the reasons why threading support is not available in gcc builds for the Cygwin environment.
http://thread.gmane.org/gmane.os.cygwin/106289/focus=106296 On March 13th of this year Herb Sutter posted a `Trip Report' on the March 2010 ISO C++ Standards Meeting (Pittsburgh, PA, USA on March 8-13, 2010) announcing that, at this meeting, the Committee approved the current draft text of C++0x as Final Committee Draft (FCD), effectively meaning that "assuming all goes well, C++0x could officially be published as soon as next year as ISO C++ 2011." One consequence of this is that conforming implementations will be required to implement threading support in the new standard C++11 libraries <thread>, etc. and, being ahead of the game, gcc already provides a (currently incomplete) implementation of the C++11 threading libraries (see: http://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.200x) which is not available to current Cygwin users. For future Cygwin implementations this is very likely still a PTC, and perhaps someone on this mailing list could confirm this, or otherwise. (Unfortunately I don't have the necessary knowledge/skills to offer my own help, as I would have liked to, but merely wanted to flag this up as a future issue all the same.) To reiterate, whilst at present the absence of full threading support in the Cygwin environment merely means that certain desirable features are not available to C++ developers using gcc under Cygwin, it will become an issue of standards compliance with the introduction of C++11.
