+/*
+ * On GNU/Linux distributions which allow to use both 2.4 and 2.6 kernels
+ * there is SYS_utimes syscall defined at compile time in glibc-kernheaders but
+ * it is available on 2.6 kernels only. Therefore, we can't rely on syscall at
+ * compile time but have to check that behaviour during program execution. An easy
+ * workaround is to have replacement for utimes() implemented within our wrapper and
+ * do not rely on syscall at all. Thus, if REPLACE_UTIME is defined already (by packager),
+ * skip these syscall shortcuts.
