Hm, I found out how to do it. Unfortuently it seems to segfault when using 
"changeword(`#<\([_a-zA-Z0-9]*\)>)')", and then trying to invoke a macro:

(gdb) run gpp.m4
Starting program: /usr/local/bin/m4 gpp.m4
Got object file from memory but can't read symbols: File truncated.





Program received signal SIGSEGV, Segmentation fault.
next_token (address@hidden, address@hidden) at input.c:918
918           if (regs.start[1] != -1)
