Do not use sprintf(), use g_snprintf() or g_strdup_printf()
(and see below).

The error probably comes from implicitly declared _().
When a C function is not declared, the compiler invents an
implicit declaration with int return value -- and you
definitely want to tell it to make a lot noise instead, for
gcc it's

  -Werror-implicit-function-declaration

and for MSVC it's

  #pragma warning(error:4013)

_() is a common convenience macro defined

  #define _(x) gettext(x)

but it's up to you to define it.

Why you mark "%02d.%02d.%d" as translatable anyway?  Either
the format is fixed and then it must not be translated, or
you want it translatable for some reason, but then you never
know how c_str needs to be long, so use g_strdup_printf().
