The Perl header "syslimits.ph" got lost between Etch and Lenny
because of a change in gcc.
>From the build log:
# convert required header files
cd /usr/include; /build/buildd/perl-5.10.0/perl.static -I
/build/buildd/perl-5.10.0/lib \
/build/buildd/perl-5.10.0/utils/h2ph -a -d
/build/buildd/perl-5.10.0/debian/tmp/usr/lib/perl/5.10 \
`cat /build/buildd/perl-5.10.0/debian/headers`
Can't open syslimits.h: No such file or directory
As of 4.2.0 or so, gcc's search path has a new "include-fixed"
directory, which contains <syslimits.h> and a few others.
h2ph doesn't look there, so syslimits.ph generation fails.
http://gcc.gnu.org/ml/gcc-patches/2007-02/msg02038.html
The attached patch fixes this; I'll send it upstream next.
Given that we haven't received a single bug report about this, it's
questionable whether <syslimits.h> actually needs to be converted.
I'm inclined to keep it but would certainly welcome other opinions.
The header conversion in debian/rules ignores all errors, probably
because h2ph -a will exit with a non-zero status if any files cannot be
found during the recursion. There are normally a few other missing files:
Can't open machine/ansi.h: No such file or directory
Can't open sys/_types.h: No such file or directory
Can't open gnu/stubs-32.h: No such file or directory
which are harmless because they are #ifdef'd out on the corresponding
architecture (which h2ph doesn't grok).
I noticed this while experimenting with the header checking patch in
#511848, so applying that should make sure headers aren't lost again
accidentally.
