How to fix "No manual entry for gcc"?

Question

I somehow lost the man pages for gcc and g++. I'm not sure where/what to look for. I'm pretty sure the man pages used to work some time ago. It also works on my Mac at work where I use roughly the same setup. Could it be a problem with brew? Or is it a bug in the XCode Command Line Tools?

Update: I just tried to re-install the XCode Command Line Tools. No luck.

~
✓  man gcc
No manual entry for gcc

~
✗  which gcc
/usr/bin/gcc

~
✓  gcc --version

gcc isn't installed anymore by Xcode, it really installs clang and calls it gcc

usxxplayegm1:~ grady$ which gcc
/usr/bin/gcc

usxxplayegm1:~ grady$ /usr/bin/gcc --version

you need man clang

I thought it was a symlink, but ls -l doesn't list it as a symlink, so either it is a hard link or some other sort of trickery.
