Source: perl
Version: 5.14.0-1
Severity: important

As discussed in
<http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2011-05/msg01275.html>

perl 5.14 triggers some compiler warnings which are sometimes converted
into errors. For example in linux-2.6:

gcc -o util/scripting-engines/trace-event-perl.o -c -fno-omit-frame-pointer -ggdb3 -Wall -Wextra -std=gnu99 -Werror -O6 -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Wformat-y2k -Wshadow -Winit-self -Wpacked -Wredundant-decls -Wstrict-aliasing=3 -Wswitch-default -Wswitch-enum -Wno-system-headers -Wundef -Wwrite-strings -Wbad-function-cast -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wold-style-definition -Wstrict-prototypes -Wdeclaration-after-statement  -fstack-protector-all -Wstack-protector -Wvolatile-register-var -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Iutil/include -Iarch/x86/include -DLIBELF_NO_MMAP -DDWARF_SUPPORT -I/usr/include/slang -DHAVE_CPLUS_DEMANGLE -DNO_STRLCPY -DSHA1_HEADER='<openssl/sha.h>'   `perl -MExtUtils::Embed -e ccopts 2>/dev/null` -Wno-redundant-decls -Wno-strict-prototypes -Wno-unused-parameter -Wno-shadow util/scripting-engines/trace-event-perl.c
