build modular Xorg failed: 'EBADF' undeclared

[Carlos Eduardo Rodrigues Diógenes]

Hi,

I was trying to compile the modular xorg from head, but I received the
following error:

gcc -DHAVE_CONFIG_H -I. -I. -I../include -I../include -I../include

WaitFor.c:268: error: (Each undeclared identifier is reported only once

WaitFor.c:274: error: 'EINVAL' undeclared (first use in this function)
WaitFor.c:279: error: 'EINTR' undeclared (first use in this function)
make[1]: *** [WaitFor.lo] Error 1

Where EBADF, EINVAL and EINTR are declared?

Thanks,
