failed to compile a C++ SPI function

Just for fun I changed the extension of my SPI function and trigger
source file from .c to .C and tried to compile it:

> g++ -g -Wall -I /usr/include/postgresql -fPIC -pedantic -c -o bid_control.o bid_control.C
> In file included from /usr/include/postgresql/nodes/relation.h:18,
> from /usr/include/postgresql/executor/spi.h:18,
> from bid_control.h:31,
> from bid_control.C:21:
> /usr/include/postgresql/nodes/parsenodes.h:871: parse error before `typename'

It seems the "typename" word used in the following structure is a
reserved word in C++. (and is appears colored like a type in Vim)

> /*
> * ParamNo - specifies a parameter reference
> */
> typedef struct ParamNo
> {
> NodeTag type;
> int number; /* the number of the parameter */
> TypeName *typename; /* the typecast */
^^^^^^^^^
> List *indirection; /* array references */
> } ParamNo;

Is it totally unreasonable try C++ in SPI programming?
