for it from compiler.mk.
Move the variable of the same name used by compiler/gcc.mk and
the gcc* buildlink3 files into private namespace (_USE_GCC_SHLIB).
already in lang/gcc34:
1) Locate adalib for bootstrap compiler with ${ALT_GCC} --print-file-name=adalib
rather than find. This behaves better if ${ALT_GCC} does not specify
a gcc executable.
2) Elide trailing letters from GCC_PLATFORM so that GCC_ARCHSUBDIR
remains constant for CURRENT when the version letter changes.
as x86_64--netbsdelf when it is identified as x86_64--netbsd.
2) Check the version of as using the just-computed ${AS_PATH}, not ${AS},
following the change to gcc3/Makefile.common submitted by jlam@netbsd.org
1) Test and mkdir if necessary to correct problem reported by
Matthias Drochner: "For me (using ALT_GCC), the directory .work/.gcc was
not present at pre-configure time, which made some "cd" fail."
2) Makefile and pkglint cleanup as recommended by Lubomir Sedlacik
fixed in the 3.4.1 branch. The third only applied to c++.
2) Remove USE_GCC33ADA option because it does not work. The gcc3-ada
compiler can be used as an Ada bootstrap compiler by specifying
ALT_GCC
3) Incremented PKGREVISION
2) Added CONFIGURE_ARGS+=--with-system-zlib logic to Makefile for
consistency with gcc34
3) Incorporated logic from gcc3 that determines whether to add
binutils dependency or not.
4) Eliminated hardcoded target of netbsdelf2.0 as a step toward supporting
other architectures.
