Hi! When I build gcc and libc headers should not be aviable at configure stage. Libsupc++' configure fails and aborts compiler building. I need libsupc++ only. After some research I find 2 cause: 1) <include > which not used in base type size checks 2) abort if time.h not found I change configure script with sed and got working compiler. Why are that checks used? You can look at my build script here - https://github.com/fedor4ever/GCC-4-Symbian Fiodar Stryzhniou
