not really, if you read the corresponding header file (gmodule.h),
you'll find this:
#ifdef G_OS_WIN32
#define g_module_open g_module_open_utf8
#define g_module_name g_module_name_utf8
#endif

that's to say: when g_module_open funtion is defined in the source code,
what is really done is defining g_module_open_utf8 if G_OS_WIN32 flag is
defined...
g_module_open is undefed, so that when the "second" definition of
g_module_open function occurs, it is its real definition...

it depends on your OS, though :)
if we don't know what OS you're running, it'll be hard to help you.
did you compile glib on your own or did you install a package/binary ?

if we consider that G_OS_WIN32 is defined, what will be called is the
second one in the code, and this will call the first one, which "real"
name is g_module_open_utf8 in this case...

as explained above, it's the first one which is named g_module_open_utf8
if G_OS_WIN32 flag is defined...

Hope that helps,
