Problem building xserver 1.5.1

[Diego A. Fons]

Hi,

I'm trying to build X as minimal as possible and I had this error:

gcc -DHAVE_CONFIG_H -I. -I../../../../include -I../../../../hw/xfree86 
-I../../../../hw/xfree86/include -I../../../../hw/xfree86/common

'__attribute__' before 'pci_power_t'
linuxPci.c:553: warning: no previous prototype for 'xf86AccResFromOS'

I'm crosscompiling for ARM in a scratchbox environment:
    gcc 4.2.4
    glibc 2.3.3

In this discussion [1] they say something about headers problem, can it 
be possible? how can i manage this error?

Best regards,
Diego A. Fons.
