This is a bug report for perl from Niko Tyni <ntyni@debian.org>,
generated with the help of perlbug 1.39 running under perl 5.13.6.


-----------------------------------------------------------------
Commit c427f4d2d4575fbc8a5190932fe321136c7597b3 in 5.10.1 made sprintf()
ignore LC_NUMERIC with numeric constants.

perl -Mlocale -MPOSIX=locale_h -e 'setlocale(LC_NUMERIC, "fi_FI") or die; printf("%s should be %g\n", sprintf("%g", 2.4), 2.4)'
2.4 should be 2,4

(At least de_DE and sv_SE should also do for the locale.)

The bug is with constant folding, this works:

perl -Mlocale -MPOSIX=locale_h -e 'setlocale(LC_NUMERIC, "fi_FI") or die; $in = 2.4; printf("%s should be %g\n", sprintf("%g", $in), 2.4)'
2,4 should be 2,4

Proposed patch attached, including a regression test. The test requires
the patches from [perl #78452] to be applied first.
