On MacOS if your path is such that gcc is the gnu gcc rather than Apple's
gcc then ./configure gives
checking whether we are cross compiling... configure: error: in
`/Users/gcolpitts/downloads/ghc-7.10.2.20151114':
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details
I worked around this by doing
export PATH=/usr/bin:$PATH
before doing ./configure
After that the install worked fine.
Thanks

Hello everyone,
We are pleased to announce the third release candidate of GHC 7.10.3:
https://downloads.haskell.org/~ghc/7.10.3-rc3/
There have been a few changes since -rc2,
* The newly-introduced readelf configure check has been disabled on non-ELF platforms
* Some tracing output from the typechecker that was causing some testsuites to fail was removed
* A latent bug in call arity analysis (#11064) is fixed
* A code generation bug (#10870) in the PowerPC NCG is fixed
* A bug in the treatment of foreign calls during demand analysis (#11076) which had affected GHCJS is fixed
* A bug in the x86 NCG causing invalid assembly to be produced when compiling with `-g` is fixed.
At this moment you will find the source tarball, as well as, 64-bit Windows, Mac OS X, 32- and 64-bit modern Linux (built on Debian 8) binary distributions available at the above URL. As usual, you may need to work around our content delivery network's update latency by adding redundant forward-slashes to the URL.
It has come to our attention that there still may be some issues with long command lines on Windows with this release: While the toolchain upgrade included in this release has the response file support necessary to work around this limitation, the version of the Cabal library shipped with this release does not. Unfortunately, the fix [1], which affects Cabal's haddock integration, has not yet shipped in a Cabal release. If you encounter this issue you might consider installing Cabal and cabal-install from git.
Lastly, I'd like to take a moment to acknowledge Futureice [2], who have donated a brand new Mac Mini for use by GHC developers to help support this platform. Their generosity is the reason we are able to offer OS X builds to you today.
Many thanks to Futureice for this donation!
Happy testing!
Cheers,
- Ben
