Commits on Oct 9, 2024

  1. Require C11 

    Error out if the compiler does not support C11.

Also removes support for `__thread` since we now rely on C11 `_Thread_local`.

  2. Replace typeof() with size_t in loop header

  3. Add feature test macro _POSIX_C_SOURCE to enable fileno() 

    Flex prior to 2.6.6 uses fileno() but does not define the needed
feature test macros.
See westes/flex#263 for details.

  5. Enable nanosleep with _POSIX_C_SOURCE 

    Move calls to nanosleep out of headers and add the feature test macro
_POSIX_C_SOURCE to enable its use. This should not cause
any significant overheads.

  6. Reduce_local test: Add feature test macros 

    Needed for strsep(), posix_memalign(), and getopt().

Also fix the min/max macros. There is no need to cache the variables
as these macros are used without producing side-effects.
