Compiling problem IRremoteInt.c

i have a problem compiling in IRremoteInt.c

C:\Users\mark\Documents\Arduino\libraries\IRremotew\IRremoteInt.c:202: error: 'RAWBUF' undeclared here (not in a function)

Can you please post your whole program here and provide a link to where you got the library.
Using a file with a .c extension seems odd in a C++ programming environment,
