gcc 4.0.0 cannot be bootstrap-ed if ./configure was run with --enable-static
--disable-shared.
This is due to the bug in "gcc/config/darwin.h".
317 /* -dynamiclib implies -shared-libgcc just like -shared would on
linux. */
318 #define REAL_LIBGCC_SPEC \
319 "%{static|static-libgcc:-lgcc}\
320 %{!static:%{!static-libgcc:\
321 %{!Zdynamiclib:%{!shared-libgcc:-lgcc}\
322 %{shared-libgcc:-lgcc_s -lgcc}} %{Zdynamiclib:-lgcc_s -lgcc}}}"
The REAL_LIBGCC_SPEC states that libgcc.a AND libgcc_eh.a are required for
static gcc.
(Probably copied from linux or i386 or any other spec files.)
However, in powerpc-apple-darwin7.7.0 (and possibly any of powerpc*-*-darwin*)
this "libgcc_eh.a" is not build during the bootstrap procedure (and also not
required).
So, after the first xgcc is build, bootstarp fails at stage1 by the following
error:
/usr/lib/ld: can't locate file for: -lgcc_eh
To fix, simply sed -e 's/ -lgcc_eh//' the gcc/config/darwin.h file.
