macro gh_init from /usr/include/guile/gh.h has a syntax error

Binary package hint: guile-1.6-dev

The macro gh_init from /usr/include/guile/gh.h has a syntax error that becomes aparent when you try to use it.

C code
#include <guile/gh.h>
void main()
{
    gh_init();
}

results in
error: syntax error before ‘)’ token
error: command 'gcc' failed with exit status 1

$ gcc --version
gcc (GCC) 4.0.3 (Ubuntu 4.0.3-1ubuntu5)

The macro definition is:
#define gh_init () scm_init_guile ()
The space after gh_init is the problem, it should really be
#define gh_init() scm_init_guile ()
