Question on mips-linux xross compilation

I am having mips-linux cross compiler toolchains installed on my machine.

m trying to compile my code which includes the system header

But the G++ compiler is cribbing for a particular line in this header

(line no 256).
The erro is "parse error before string constant".
Basically it is not liking 2 extern declaratives in front of the function void * resume().
Pls note one extern comes from asmlinkage definition which is defined as extern "C".

Pls help me out in this if u have any idea..

thanks in advance.
