Binaries with names like 'run' or 'service' are likely to conflict.
Warn about these and suggest a libexec-style install instead.

A better fix would be to rewrite the curl method to yield its output,
but I don't feel like doing that right now.

This is a string since it is used to match string keys in a hash.

The other values will be identical.

The one liner should put `#{HOMEBREW_PREFIX}/bin:$PATH` into bash profile.
Previously it was being interpreted by the shell before being put in bash profile.

This causes CI builds on 10.9 to fail; will repush once it is updated.

This reverts commit 70c5ce09d995426aefdbfd4aba0b06efe100a433.

The cc wrapper's make_fuss is only enabled when HOMEBREW_CCCFG contains
'O', which is set by the make wrapper. This means it is disable when
running configure scripts. However, this does not include configure
scripts invoked by make, which inherit the value of HOMEBREW_CCCFG from
the make process. make_fuss will be enabled for these scripts, cause
breakage.

Configure scripts generated by autoconf 2.56 (November 2002) or later
export DUALCASE into the environment of subprocesses. This variable is
only used by the MKS shell, so we can use it as a heuristic to determine
if we are running as a subprocess of a configure script.

The default mode is intended to display recursive dependencies, with the
`--1` flag to display only one level.

* In certain cases, a C++ software may result in linking to a different
  and incompatible C++ standard library than its dependencies and still
  works fine because it is by design. Examples include GCC, which will
  bootstrap itself and self-host after finish.

* Add a cxxstdlib_check method to formula to request changing the C++
  standard library checking. Currently using "cxxstdlib_check :skip"
  will let a formula skip such checking. This should only be used on
  rare occasions and be very careful.

* This is consistent with superenv.
