* Use appveyor.yaml from c++11 branch so that CI run ok. * Use .travis.yml from the c++ branch so that Travis CI jobs run ok. * Add c++11 scripts and Linux config so that Travis CI jobs are ok. * Use mkdocumentation & mkrelease from c++11 branch. * Use PocoDoc config files from c++11 branch. * define POCO_ENABLE_C11 as the default * CMake: ignore Crypto for now. To be fixed since it fails. * Backport c++11 changes from the c++11 branch * Add Cygwin config with c++11 setup. * Update appveyor.yml from c++11 branch.

# These macros are defined by all GNU compilers that use the C preprocessor: C, C++, Objective-C and Fortran.

# Their values are the major version, minor version, and patch level of the compiler, as integer constants.

# For example, GCC 3.2.1 will define __GNUC__ to 3, __GNUC_MINOR__ to 2, and __GNUC_PATCHLEVEL__ to 1. i

# at least the release number.
