Mac OS X w/ Xcode 5.1.1: error: unknown type name 'FILE'

I've installed llvm using brew:
brew install --with-clang --all-targets --rtti --universal --jit llvm
brew link llvm --force
error:
cc -std=c99 -I/usr/local/Cellar/llvm/3.4/include -D_DEBUG -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -O3 -fno-common -Wall -Wextra -pedantic -O3 -I./src -c -o src/obj/completion_serv.o ./src/completion_serv.c

How can I install the type name 'FILE' ?
