On MSYS2, mingw can be used in two ways [1]: - with MSVCRT as runtime library (this is also what mingw on Cygwin does), - with UCRT as runtime library (same runtime library as used by MSVC).
Comparing the config.cache values of a gnulib testdir in both cases, I see some small differences. For example, the timespec_get function is supported in UCRT but not in MSVCRT. This patch adapts the documentation.
