Environment: OS X 10.9 (Mavericks) and Xcode 5.0
Command line compilations/links fail with either:
"catastrophic error: cannot open source file "stdlib.h" OR with "ld: library not found for -lcrt1.10.6.o"
Affected compiler: Intel Composer XE 2013 Update 1
Root cause: Xcode 5.0 installation does not install all command line tools (include files, libraries, SDKs) need for the compiler to link user applications.
