With GHC MR !8478, GHC is able to spot a redundant pattern match
when RLIM_SAVED_CUR == RLIM_SAVED_MAX, which it wasn't able to
detect before. So we use considerAccessible to avoid a pattern match
check. This unfortunately means we must change the SafeHaskell status
of that module to TrustWorth, as considerAccessible is from GHC.Exts,
which isn't safe.

Alternatives:

  - we can't perform the equality test RLIM_SAVED_CUR == RLIM_SAVED_MAX
    using CPP macros, because one of the values might expand out to
    have casts;
  - turning off pattern match warnings impacts warnings across the whole
    module, instead of the single affected function,
  - adding a dummy equation such as "id True" to the first pattern match
    would work, but seems more ad-hoc.

* Add regression test for #218

https://github.com/haskell/unix/issues/218



Error was:

uncaught exception: IOException of type InvalidArgument
semTrywait: invalid argument (Bad file descriptor)

* Fix 'semTrywait: invalid argument (Bad file descriptor)' wrt #218

* Add regression test for putEnv wrt #68

* Synchronize ByteString and String modules

And fix free-bug in 'putEnv'. Fixes #68

* Add cabal.project

* Fix the error handling of posix_fallocate other than FreeBSD

This commit introduces a CPP guard to take care of the difference
between OSes of the errors of posix_fallocate.

On Linux and NetBSD, posix_fallocate reports error by returning an error
number. errno is not set.
On the other hand, on FreeBSD, posix_fallocate returns -1 and sets
errno.

The existing code could handle FreeBSD-style errors only.

* Remove obsolete FreeBSD-style error handling

The FreeBSD-style error (return -1, set errno) is obsolete as of
FreeBSD 11.0; it now reports errors as same as the other OSes.

* Future-proof glibc version check

* Resource: Fix warning in case of no RLIM_SAVED_{CUR,MAX}

This previously failed to build with a warning on FreeBSD 11.2

* Bump to 2.7.3

* Add Eq and Show instance to BaudRate

Needed for test suite

* Add CI

* Tighten lower base bound to only allow GHC-8.2+

Bump base upper bound

Bump base upper bound to 4.15

testsuite: Mark posix002 as fragile in all concurrent_ways

Testsuite changes for GHC 8.10

Previously we only marked it as broken in threaded2, but this missed
some cases.

As noted in GHC #11645 and #8842, forking and profiling don't go well
together.

As noted in ghc/ghc#16814, this test is remarkably fragile
when run concurrently.

However the check similarly to tell and seekdir succeeds. However we will generate the following error down the line:

Autoconf hasn’t had an update since 2014, and it doesn’t look like it will soon[1]
This updates config.{guess,sub}

It basically does exactly what the config.guess script says:
> It is advised that you download the most up to date version of the config scripts from

It adds support for e.g. `-ios`, which allows to have targets like `aarch64-apple-ios`.

Android doesn’t have telldir/seekdir in bionic

The isse here is that while we try to use `AC_CHECK_FUNCS`, this will generate test code
that tries to link an object and check for linking errors.  However  GNU gold at least version
(binutils-2.25-0666073 2.25.51.20141117) 1.11, considers seekdir/telldir as part of the
default libs. Thus we would actually want to pass `-nodefaultlibs` to the linker. Doing so,
would result in erros due to not finding `-ldl`.

Fixes #91

Define _POSIX_VDISABLE, if not defined.
