a problem while compiling libcap

Hello,
My operating system is Linux FC 6.
I downloaded 2.6.16.11 version of Linux kernel, then added patch and compiled the kernel. This patch was supposed to add new capabilities to my kernel. However, to achieve this goal I have to compile libcap.
I downloaded source code of libcal from www.kernel.org, unpacked it into my home (I logged in as a root) directory and ran make. Unfortunately make halted with error message. Here is outupt:

Code:

[root@localhost libcap-1.10]# make
make -C libcap CC='gcc' CFLAGS='-Dlinux -ansi -D_POSIX_SOURCE -Wall -Wwrite-strings -Wpointer-arith -Wcast-qual -Wcast-align -Wtraditional -Wstrict-prototypes -Wmissing-prototypes -Wnested-externs -Winline -Wshadow -pedantic -g   -I/home/bayram/libcap-1.10/libcap/include' LD='ld' LIBS='-L/home/bayram/libcap-1.10/libcap -lcap' LDFLAGS='-s ' VERSION='1' MINOR='10' LIBDIR='/lib' INCDIR='/usr/include' SBINDIR='/sbin' MANDIR='/usr/man' all

[root@localhost libcap-1.10]#

Then I copied the file compiler.h to /usr/include/linux/ and ran make. However,make again failed with the following output:

Code:

[root@localhost libcap-1.10]# make

Could anyone help me with this problem?
Thank you in advance.
