The CC variable specifies the C compiler executable to use and nothing else. You need to alter the CFLAGS variable to alter the compile flags, you can't cram them in there.

pth-config

PTH-CONFIG(1)						       GNU Portable Threads						     PTH-CONFIG(1)

NAME

       pth-config - Pth library build utility

VERSION

       GNU Pth 2.0.7 (08-Jun-2006)

SYNOPSIS

       pth-config [--help] [--version] [--all] [--prefix] [--exec-prefix] [--bindir] [--libdir] [--includedir] [--mandir] [--datadir] [--acdir]
       [--cflags] [--ldflags] [--libs]

DESCRIPTION

       The pth-config program is a little helper utility for easy configuring and building applications based on the pth(3) library.  It can be
       used to query the C compiler and linker flags which are required to correctly compile and link the application against the pth(3) library.

OPTIONS

       pth-config accepts the following options:

       --help
	   Prints the short usage information.

       --version
	   Prints the version number and date of the installed pth(3) library.

       --all
	   Forces the output of all flags, that is, including extra flags which are not Pth specific.

       --prefix
	   Prints the installation prefix of architecture independent files

       --exec-prefix
	   Prints the installation prefix of architecture dependent files.

       --bindir
	   Prints the installation directory of binaries.

       --libdir
	   Prints the installation directory of libraries.

       --includedir
	   Prints the installation directory of include headers.

       --mandir
	   Prints the installation directory of manual pages.

       --datadir
	   Prints the installation directory of shared data.

       --acdir
	   Prints the installation directory of autoconf data.

       --cflags
	   Prints the C compiler flags which are needed to compile the pth(3)-based application. The output is usually added to the "CFLAGS" vari-
	   able of the applications "Makefile".

       --ldflags
	   Prints the linker flags ("-L") which are needed to link the application with the pth(3) library. The output is usually added to the
	   "LDFLAGS" variable of the applications "Makefile".

       --libs
	   Prints the library flags ("-l") which are needed to link the application with the pth(3) library. The output is usually added to the
	   "LIBS" variable of the applications "Makefile".

EXAMPLE

	CC	= cc
	CFLAGS	= -O `pth-config --cflags`
	LDFLAGS = `pth-config --ldflags`
	LIBS	= -lm `pth-config --libs`

	all: foo
	foo: foo.o
	    $(CC) $(LDFLAGS) -o foo foo.o $(LIBS)
	foo.o: foo.c
	    $(CC) $(CFLAGS) -c foo.c

SEE ALSO

       pth(3), cc(1).
