I found two problems there. One is that I forgot postgres.h include in
common.c. it is easy to fix. However second problem is more complicated.
dumputils.c calls ScandKeywordLookup function which is defined in
keyword.c. :(

I currently see two possible variant:

1) Put list of RESERVED keyword into dumputils and use bsearch for
lookup. It is easy to implement but it will be difficult to keep
synchronize these two list together.

2) Modify gram.y to generate parse.h which will be friendly for backend
and can be used in keyword.c. Probably add some ifdef ...

3) Put following fake into keyword.c before include "parse.h" line. It
is easiest way.

#define TYPE_IS_DECLARED 1
#define YYLTYPE_IS_DECLARED 1
#define YYLTYPE void*
#define YYSTYPE void*

Comments or any ideas?
