Hello, deeptech71. You wrote 9 =D0=B0=D0=BF=D1=80=D0=B5=D0=BB=D1=8F 2013 =D0=B3., 3:06:42: d> There are some issues when building "updated" sources [1].

Ok, World build time was reduced from 1:27 to just 0:27. building clang and binutils twice takes one hour (!!!!!)? or 2/3 of buildworld time!. But, of course, headers should be equivalent to ones in sources. Also, disabled binutils lead to inability to install worils (install -s doesn't work). Returning binutils to build (to allow `install -s' works) yelds only 1 or 2 minutes, Ok. It is very sad, that external compiler cannot be used with "fresh" sources (when headers are different). We need some solution for this, for sure! When compilers are identical (same clang revision), but sources has updated headers. It does proper trick with libraries, but not with headers! Also, it should be possible to use system strip in such case. --=20 // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
