[CentOS] kernel.h error stdarg.h

Hello,

if compiling the driver for my ralink wlan card or compiling the driver for my 5-1 card reader, I get the following error message.

./include/linux/kernel.h:10:20: error: stdarg.h: No such file or directory

Is there something broken on my system?

# rpm -qa | grep kernel kernel-devel-2.6.18-53.1.14.el5 kernel-headers-2.6.18-53.1.14.el5 kernel-2.6.18-53.1.14.el5

# uname -a Linux hobbingen 2.6.18-53.1.14.el5 #1 SMP Wed Mar 5 11:36:49 EST 2008 i686 i686 i386 GNU/Linux

Thank you Olaf
