There seems to be quite a few issues with Homebrew compilation after upgrade to Yosemite.
While some of them are easily fixed by upgrading relevant GCC packages, one problem kept me from upgrading my macvim for a while.
Short version: if after upgrading all the gcc related packages you still get errors on Yosemite, try upgrading python as well.

There seems to be quite a few issues with Homebrew compilation after upgrade to Yosemite.
While some of them are easily fixed by upgrading relevant GCC packages, one problem kept me from upgrading my macvim for a while.
Short version: if after upgrading all the gcc related packages you still get errors on Yosemite, try upgrading python as well.
Compiling macvim produced the following error:

These open issues may also help:
macvim failed to build on 10.9 because of x11 (https://github.com/Homebrew/homebrew/issues/30253)
That issue #30253 turned out not to be relevant.
On the surface it looked like its a common yosemite gcc problem, but even after upgrading all to latest it didn’t work.
Next I tried ‘brew upgrade -v macvim’
✗ brew upgrade -v macvim

Looking in the 01.configure.cc I found the following:
clang called with: -I/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/include/python2.7 -I/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/include/python2.7 -fno-strict-aliasing -fno-common -dynamic -I/usr/local/include -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -arch x86_64 -L/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config -ldl -framework CoreFoundation -lpython2.7 -u _PyMac_Error Python.framework/Versions/2.7/Python conftest.c

so I just created a very simple foo.c file and tried to compile it with the
same gcc arguments:
✗ clang -I/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/include/python2.7 -I/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/include/python2.7 -fno-strict-aliasing -fno-common -dynamic -I/usr/local/include -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -arch x86_64 -L/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config -ldl -framework CoreFoundation -lpython2.7 -u _PyMac_Error Python.framework/Versions/2.7/Python foo.c
clang: error: no such file or directory: 'Python.framework/Versions/2.7/Python'
Note the Python.framework/Versions/2.7/Python part. it seems to be relative
and not the full path. Digging a bit on the internet python turned out to be
the problem.
After removing and re-installing python all turned out to work. The same part
01.configure.cc after python upgrade:
clang called with: -I/usr/local/Cellar/python/2.7.8_2/Frameworks/Python.framework/Versions/2.7/include/python2.7 -I/usr/local/Cellar/python/2.7.8_2/Frameworks/Python.framework/Versions/2.7/include/python2.7 -fno-strict-aliasing -fno-common -dynamic -I/usr/local/include -I/usr/local/opt/sqlite/include -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -L/usr/local/Cellar/python/2.7.8_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config -ldl -framework CoreFoundation -lpython2.7 conftest.c
