Dear monks:

I'm making a perl module to wrap a library. Everything goes well, until I added typemap for this enum. This is the enum:

namespace geno_eye
{

typedef enum
{
    LABEL_BIND_TOP = 1,
    LABEL_BIND_BOTTOM = 1 << 1,
    LABEL_BIND_LEFT = 1 << 2,
    LABEL_BIND_RIGHT = 1 << 3
} LabelBind;

}

and this is the typemap. I attempt to convert it from/to string for perl SV: 
geno_eye::LabelBind  GENO_EYE_LABEL_BIND_T

INPUT
GENO_EYE_LABEL_BIND_T
    char* sv_text = SvPV_nolen($arg);
    $var = 0;
    if (strstr(sv_text, "top") || strstr(sv_text, "TOP"))
        $var |= geno_eye::LABEL_BIND_TOP;
    else if (strstr(sv_text, "bottom") || strstr(sv_text, "BOTTOM"))
        $var |= geno_eye::LABEL_BIND_BOTTOM;
    if (strstr(sv_text, "left") || strstr(sv_text, "LEFT"))
        $var |= geno_eye::LABEL_BIND_LEFT;
    else if (strstr(sv_text, "right") || strstr(sv_text, "RIGHT"))
        $var |= geno_eye::LABEL_BIND_RIGHT;

OUTPUT
GENO_EYE_LABEL_BIND_T
    if ($var|geno_eye::LABEL_BIND_TOP)
        sv_setpv($arg, "top");
    else if ($var|geno_eye::LABEL_BIND_BOTTOM)
        sv_setpv($arg, "bottom");
    
    if ($var|geno_eye::LABEL_BIND_LEFT)
        sv_catpv($arg, "left");
    else if ($var|geno_eye::LABEL_BIND_RIGHT)
        sv_catpv($arg, "right");

I wrote a minimum test XS file:

#ifdef __cplusplus
extern "C" {
#endif

#include "EXTERN.h"
#include "perl.h"
#include "XSUB.h"
#include "ppport.h"

#undef do_open
#undef do_close

#ifdef __cplusplus
}
#endif

#include "geno_eye_perl.h"

#include <exception>
#include <iostream>

#undef  xsp_constructor_class
#define xsp_constructor_class(c) (c)

#include <geno_eye/common.h>

MODULE=Test PACKAGE=Test

void test(geno_eye::LabelBind value)
    CODE:
        std::cout << "binary value: " << value << std::endl;

When I run perlxs, it cries at the first code line of the INPUT section: 
$ xsubpp -typemap test_typemap test.xs >test.cpp

    if (strstr(sv_text, "top"
  (Might be a runaway multi-line "" string starting on line 1)
    (Missing operator before top?)

        $var |= geno_eye::LABEL_BIND_TOP;
    else if (strstr(sv_text, ""
