Subject: [PATCH] libstdc++: Check for TLS support on mingw cross-compilers
|
|
|
|
Native mingw builds enable TLS, but crosses don't because we don't use
|
|
GCC_CHECK_TLS in the cross-compiler config.
|
|
|
|
libstdc++-v3/ChangeLog:
|
|
|
|
* crossconfig.m4: Check for TLS support on mingw.
|
|
* configure: Regenerate.
