on how to compile gcc-4.6 correctly?

[Dennis, CHENG Renquan]

For anyone could succeed compiling gcc-4.6, could you paste a correct
ggc_alloc_cleared_lang_type macro ?

just run this grep command under your build directory,

gcc-4.6-build$ grep -RsInw ggc_alloc_cleared_lang_type gcc/
gcc/gtype-desc.h:2451:#define ggc_alloc_cleared_lang_type() ((struct
lang_type *)(ggc_internal_cleared_alloc_stat (sizeof (struct
lang_type) MEM_STAT_INFO)))

thanks,
