Subject: In GLX_USE_TLS builds, make GET_CURRENT_CONTEXT use the TLS verion of the
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6cae4f3bc9b92f9bbda753843e8ff0f0bbbb8fb3;p=mesa.git

In GLX_USE_TLS builds, make GET_CURRENT_CONTEXT use the TLS verion of the
variable.  Without this, GET_CURRENT_CONTEXT would *always* result in a call
to _glapi_get_context (because _glapi_Context is a const pointer to NULL in
TLS builds).
