Any workaround?

Same issue in 15.10 under Gnome 3.16.4

from xserver-xorg-input-synaptics.

Same issue in 15.10-gnome

from xserver-xorg-input-synaptics.

The workaround is to add
#include <xorg-server.h>
to the top of synproto.h

This let make finish without errors (but with warnings).

Check your error message for file name and line number. In your case -

/usr/include/xorg/os.h:541:1:....

File - os.h
File Path - /usr/include/xorg/os.h
Line No - 541

Use your favourite text editor to open the file -

sudo vim /usr/include/xorg/os.h

So 541 is the line which is causing issue, comment it. Now you have to comment out line 540 too, why? The reason is it's a combined logic inside the if block as you can see in below:

#ifndef HAVE_STRNDUP <----- If block starts
extrn _X_EXPORT char * <----------- Comment out this line using // in front
strndup(const char *str, size_t n); <----------- Comment out this line using // in front
#endif <------ If blocks ends
