The support for TLS (Thread Local Storage) would probably come from  
the compiler itself. Windows has TLS (see for example http:// 
dotnet.di.unipi.it/Content/sscli/docs/doxygen/pal/localstorage_8c- 
source.html and http://www.ddj.com/dept/cpp/184403874, or the MSDN  
documentation at http://msdn.microsoft.com/library/default.asp?url=/ 
library/en-us/dllproc/base/tlsalloc.asp), so you'd "only" need to  
teach GCC how to call that.

Now, I don't have competence, time and motivation to do that. So, if  
my analysis above is correct, there are three things you can do: ask  
around here if someone is interested in this and is planning to do  
it; do it yourself, if you have the competence; find someone you  
know, that you have leverage on, to do it :)

Now, for an idea of how much work it represents... perhaps someone  
here can tell us?
