(IMHO, g_off_t is a non-starter).
I think I understand. How about in config.h.in
{{{
/* use own off_t definition */
#define _OFF_T_
#define _off_t off64_t
#define off_t off64_t
/* fseeko and ftello are safe because not defined by MINGW */
#define HAVE_FSEEKO
#define fseeko fseeko64
#define ftello ftello64
/* lseek is not safe, defined in io.h */
#define HAVE_LSEEK64
/* use _stati64 compatible with MSVCRT < 6.1 */
/* stat and fstat are not safe, defined in stat.h */
#define HAVE__STATI64
#define HAVE__FSTATI64
#define _STRUCT_STAT_
typedef struct _stati64 STRUCT_STAT;
}}}
in lib/gis/seek.c new function G_lseek()
{{{
off_t G_lseek(int fd, off_t offset, int whence)
{
#ifdef HAVE_LSEEK64
return lseek64(fd, offset, whence);
#else
return lseek(fd, offset, whence);
#endif
}
}}}
in lib/gis/paths.c
{{{
int G_stat(const char *file_name, STRUCT_STAT *buf)
{
#ifdef HAVE__STATI64
return _stati64(file_name, buf);
#else
return stat(file_name, buf);
#endif
}
int G_lstat(const char *file_name, STRUCT_STAT *buf)
{
#ifdef __MINGW32__
return G_stat(file_name, buf);
#else
return lstat(file_name, buf);
#endif
}
}}}
?
Then update other libs and modules accordingly...
