I do not know for sure to what extent GCC supports TLS on Windows. There are compiler extensions that can be used under Windows, like __declspec(thread) which automagically handles the declaration and initialization of the TLS variable rather than dynamically calling the TlsAlloc, TlsFree, TlsSetValue, and TlsGetValue. I also believe they have extensions in the compiler that recognize that you are using TLS (when using __declspec) and therefore allow you to access them without having to use the TlsSetValue and TlsGetValue. Sorry I don't about GCC, but I hope this additional information helps.

Goes GCC on Windows support TLS, or only Microsoft compilers? -- Bruce Momjian | http://candle.pha.pa.us [EMAIL PROTECTED] | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073 ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
