as str[n]casecmp and strndup. The definition of the prototypes is guarded<br>
by #ifndef HAVE_STRFOO, but HAVE_STRFOO is defined by xorg-server.h which<br>
is not included by all users of os.h. E.g. glamor.h does not and should not<br>
include xorg-server.h<br>
<br>
This is a problem since the these prototype declarations clash with the libc<br>
declarations when using the latest glibc:<br>

To fix this, this commit moves the HAVE_STRFOO defines to their own<br>
(generated) header called os-strfeatures.h, and unconditionally includes this<br>
header from os.h .<br></blockquote><div><br></div><div>NAK.</div><div><br></div><div>If glamor.h includes scrnintstr.h, it must include xorg-server.h. xorg-server.h (as distinct from xorg-config.h) is the specially-generated header designed explicitly to be included by all exported/SDK modules which include internal headers, since it carries defines such as _XSERVER64 (and many, many more) which thoroughly smash the server ABI.</div>
