If you have tests and they are ok then why not put it in.
It is thoroughly tested in the libstdc++ test suite, unfortunately we
have do adjust all test cases since they contain stuff like this:
// { dg-do run { target *-*-freebsd* *-*-dragonfly* *-*-netbsd*
*-*-linux* *-*-gnu* *-*-solaris* *-*-cygwin *-*-darwin*
powerpc-ibm-aix* } }
// { dg-options " -std=gnu++11 -pthread" { target *-*-freebsd*
*-*-dragonfly* *-*-netbsd* *-*-linux* *-*-gnu* powerpc-ibm-aix* } }
// { dg-options " -std=gnu++11 -pthreads" { target *-*-solaris* } }
// { dg-options " -std=gnu++11 " { target *-*-cygwin *-*-darwin* } }
// { dg-require-cstdint "" }
// { dg-require-gthreads "" }
So, there is a target white list.

The test results are not that bad. Some tests use files, which are not
available to the RTEMS test driver. The main issues are due to thread
cancel/exit misbehaviour of RTEMS. Shared mutexes are not implemented in
general.
