You mean every thread enabled program would need to distribute it, correct? Wouldn't libstdc++ be coded to be conditionally dependent on the threads library if it were available?

Although it is usually good advice to distribute the source for the binary with the binary to avoid having to store the source for X period of time. > I deem it acceptable for the use of OpenMP create a dependency on > pthreads-w32; I do *not* deem it acceptable for every C++ program to > have that dependency. > I see no harm in a C++ program using std::thread to require pthreads-w32. > It would be far preferable to me for someone to extend GCC to use > Win32 gthreads for std::thread. > Why not code pthreads to use Windows gthreads? It would get wider acceptance in GCC if the library normally used for threading with GCC is used for the implementation. Earnie P.S. The w32 and Win32 speak needs to be modified to be Windows. ------------------------------------------------------------------------------ Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.
