Hello, I'm working on a bootstrap of gcc-4.6.1 using Sun Studio on Solaris 9. I'm currently stuck at a liblto_plugin.so linking issue[1], but I'd first like to verify whether my general approach is correct. There is a mutual incompatibility between flags accepted by Sun Studio and GCC. Therefore, 2 sets of CFLAGS are needed: one for the host compiler (here: Sun Studio), and one gcc for the subsequent stages. The first one is set via CFLAGS, and the second one is set via CFLAGS_FOR_TARGET. Is this approach correct? (I also saw references to the TARGET_CFLAGS variable, so I'm not sure which one to use.)
