Missing parse_merge.h?

Hi,

I just got a compile error as below on the latest HEAD.
-----------------------
gcc -Wall -Wmissing-prototypes -Wpointer-arith
-Wdeclaration-after-statement -Wendif-labels
-Wmissing-format-attribute -Wformat-security -fno-strict-aliasing
-fwrapv -fexcess-precision=standard -g -O2 -I. -I.
-I../../../src/include  -D_GNU_SOURCE   -c -o analyze.o analyze.c

analyze.c:41:32: fatal error: parser/parse_merge.h: No such file or directory

#include "parser/parse_merge.h"

                               ^

compilation terminated.

make[3]: *** [analyze.o] Error 1
-----------------------

The latest commit [1] looks missing parse_merge.h.
Or did I make some mistake on building?
