Description

That may sound weird but that's what's happening.

On Mac OS X, the HFS file system is case-insensitive. Because of this and the order of include paths defined by $(INCLUDES) in etc/config/makefile.common, one or more of the executables for the configuration checks which have the same filename as standard header files (e.g. LIMITS) are found first and included in the source files by the compiler.

Output from an example build:

machine:_{/Build/stdcxx user$ make BUILDDIR=}/Build/stdcxx BUILDMODE=debug,shared,pthreads
GNUmakefile:283: "CONFIG not specified, using gcc.config"
creating BUILDDIR=/Users/user/Build/stdcxx
generating /Users/user/Build/stdcxx/makefile.in from /Users/user/Work/stdcxx/etc/config/gcc.config
make config
