Bug#775009: perl-base: perl is configured to use the 'cc' compiler, it should use 'gcc'

[Mikulas Patocka]

Package: perl-base
Version: 5.10.1-17squeeze6
Severity: normal

When compiling modules, perl uses the 'cc' compiler instead of 'gcc'.

If the user installs some other compiler that overrides the 'cc' command (for
example the Sun C compiler), building perl modules results in many warnings or
errors because perl calls 'cc' with gcc-like command line flags (that the cc
compiler doesn't understand) and the C code to be compiled contains gcc-like
attributes (that the cc compiler also doesn't understand). Perl-generated
makefiles should call gcc instead of cc.

Steps to reproduce:
install spamassassin
install some other compiler as cc (or, you can do ln -s /bin/false
/usr/local/bin/cc)
run sa-compile
- it calls cc and fails

cc='cc' is stored in /usr/lib/perl/5.10.1/Config_heavy.pl, but if I change it
to cc='gcc' in that file, it doesn't fix the bug.
It is unclear how the user can select a compiler for sa-compile.
