unix 2.7.1.0 * Bundled with GHC 7.10.1 * Add support for `base-4.8.0.0` * Tighten `SafeHaskell` bounds for GHC 7.10+ * Add haddock comments on `RTLD_NEXT` and `RTLD_DEFAULT` * Deprecate function `haveRtldLocal` * Fix `getGroupEntryForID/getGroupEntryForName` on Solaris. Solaris uses CPP macros for required `getgrgid_r` and `getgrnam_r` functions definition so the fix is to change from C ABI calling convention to C API calling convention * Fix potential type-mismatch in `telldir`/`seekdir` FFI imports * Use CAPI FFI import for `truncate` to make sure the LFS-version is used. * `executeFile`: Fix `ENOTDIR` error for entries with non-directory components in `PATH` (and instead skip over non-directory `PATH`-elements) * New functions in `System.Posix.Unistd`: - `fileSynchronise` (aka `fsync(2)`), and - `fileSynchroniseDataOnly` (aka `fdatasync(2)`) * New module `System.Posix.Fcntl` providing - `fileAdvise` (aka `posix_fadvise(2)`), and - `fileAllocate` (aka `posix_fallocate(2)`) * Fix SIGINFO and SIGWINCH definitions
