I just tried to bootstrap the GNU C compiler version 4.3 snapshot 20070720
with the Intel C compiler.
The Intel compiler said
../../../src/gcc-4.3-20070720/fixincludes/fixincl.c(1049): remark #593:
variable "name_len" was set but never used
../../src/gcc-4.3-20070720/gcc/c-decl.c(4708): remark #593: variable
"type_as_written" was set but never used
../../src/gcc-4.3-20070720/gcc/c-decl.c(3984): remark #593: variable
"typedef_type" was set but never used
../../src/gcc-4.3-20070720/gcc/bb-reorder.c(1227): remark #593: variable
"has_hot_blocks" was set but never used
../../src/gcc-4.3-20070720/gcc/bb-reorder.c(1528): remark #593: variable
"prev_bb" was set but never used
Here is a patch to shut up the compiler
