...or for cross-targets, breakage. Something went wrong with
this or subsequent changes; somewhere in the r183262:183268 I've
started getting:
...
Configuring in cris-elf/libstdc++-v3
configure: creating cache ./config.cache
checking build system type... x86_64-unknown-linux-gnu
checking host system type... cris-axis-elf
checking target system type... cris-axis-elf
...
checking for GNU c++filt... /usr/bin/c++filt
(right there's a buglet, but let's not get
distracted and it's a preexisting condition anyway )
checking whether the target supports .symver directive... yes
configure: versioning on shared library symbols is no
checking for size_t as unsigned int... no
checking for ptrdiff_t as int... no
checking whether the target supports hidden visibility... yes
configure: visibility supported: yes
checking for makeinfo... makeinfo --split-size=500
checking for modern makeinfo... yes
checking for doxygen... yes
checking for dot... no
checking for xsltproc... yes
checking for xmllint... yes
checking for stylesheets used in generation of documentation... no
checking for local stylesheet directory... no
checking for dblatex... no
checking for pdflatex... yes
checking for
/usr/share/xml/docbook/stylesheet/docbook-xsl-ns/epub3/chunk.xsl... configure:
error: cannot check for file existence when cross compiling
make[1]: *** [configure-target-libstdc++-v3] Error 1
make[1]: Leaving directory `/tmp/hpautotest-gcc1/cris-elf/gccobj'
make: *** [all] Error 2
For r183262 I got, around the above point of breakage:
...
configure: visibility supported: yes
checking for makeinfo... makeinfo --split-size=500
checking for modern makeinfo... yes
checking for doxygen... yes
checking for dot... no
checking for xsltproc... yes
checking for xmllint... yes
checking for stylesheets used in generation of documentation... no
checking for local stylesheet directory... no
checking for dblatex... no
checking for pdflatex... yes
checking for ruby... yes
checking for dbtoepub... no
configure: updating cache ./config.cache
checking for gxx-include-dir... no
checking for --enable-version-specific-runtime-libs... no
checking for install location...
${prefix}/${target_alias}/include/c++/${gcc_version}
configure: creating ./config.status
config.status: creating Makefile
...
Pretty please cross-test for your favorite cross-target. The
build system was running Fedora 12, FWIW.
brgds, H-P

Testing this patch, will check it in if passes, sorry.
