stage2 of the 3-stage bootstrap of the compiler are deleted as
soon as they are no longer needed.
If you want to save additional space during the bootstrap and in
the final installation as well, you can build the compiler binaries
without debugging information as in the following example. This will save
roughly 40% of disk space both for the bootstrap and the final installation.
(Libraries will still contain debugging information.)
If you wish to use non-default GCC flags when compiling the stage2
and stage3 compilers, set @code{BOOT_CFLAGS} on the command line when
doing @samp{make}. For example, if you want to save additional space

If you wish to use non-default GCC flags when compiling the stage2 and
stage3 compilers, set @code{BOOT_CFLAGS} on the command line when doing
@samp{make}. Non-default optimization flags are less well
tested here than the default of @samp{-g -O2}, but should still work.
In a few cases, you may find that you need to specify special flags such
as @option{-msoft-float} here to complete the bootstrap; or, if the

around this, by choosing @code{BOOT_CFLAGS} to avoid the parts of the

You can place non-default optimization flags into @code{BOOT_CFLAGS}; they
are less well tested here than the default of @samp{-g -O2}, but should
still work. In a few cases, you may find that you need to specify special
flags such as @option{-msoft-float} here to complete the bootstrap; or,
if the native compiler miscompiles the stage1 compiler, you may need
to work around this, by choosing @code{BOOT_CFLAGS} to avoid the parts
of the stage1 compiler that were miscompiled, or by using @samp{make
bootstrap4} to increase the number of stages of bootstrap.
Note that using non-standard @code{CFLAGS} can cause bootstrap to fail
if these trigger a warning with the new compiler. For example using
@samp{-O2 -g -mcpu=i686} on @code{i686-pc-linux-gnu} will cause bootstrap
failure as @option{-mcpu=} is deprecated in 3.4.0 and above.
@code{BOOT_CFLAGS} does not apply to bootstrapped target libraries.
Since these are always compiled with the compiler currently being
bootstrapped, you can use @code{CFLAGS_FOR_TARGET} to modify their
compilation flags, as for non-bootstrapped target libraries.
Again, if the native compiler miscompiles the stage1 compiler, you may
need to work around this by avoiding non-working parts of the stage1
compiler. Use @code{STAGE1_LIBCFLAGS} to this end.
If you used the flag @option{--enable-languages=@dots{}} to restrict
the compilers to be built, only those you've actually enabled will be

@samp{make compare} may fail on old versions of DEC Unix unless you add
@option{-save-temps} to @code{CFLAGS}. On these systems, the name of the
