Fw: Does ld removes uncalled functions from final exe ?

[Valery Pykhtin]

Hi Nick,
 
sorry, but this is not help to me :(. The info says that not all platforms
have such optimizations.
 
 My platform is Pentium 4, Red Hat Linux 9.0
gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
GNU ld version 2.13.90.0.18 20030206

Best regards,
Valery
