This is a bug report for perl from root@​siriuswx3-st-au-app.lfxau.linfox.com,
generated with the help of perlbug 1.40 running under perl 5.22.1.

ExtUtils​::CBuilder creates temp files in CWD, because no directory is specified - This causes a problem in our application.

This change should make it behave properly and create files in the platform correct temporary location.

my ( $FH, $tmpfile ) = tempfile( "compilet-XXXXX", SUFFIX => $suffix , DIR => File​::Spec->tmpdir());

$suffix );
---

my ( $FH, $tmpfile ) = tempfile( "compilet-XXXXX", SUFFIX => $suffix
, DIR => File​::Spec->tmpdir());

1. At a general level, this change seems worthwhile.

2. However, if I am reading 'perldoc File​::Temp' correctly, this change could also be written as​:

#####
my ( $FH, $tmpfile ) = tempfile(
  "compilet-XXXXX",
  SUFFIX => $suffix,
  TMPDIR => 1
);
#####

... which might be more self-documenting.

3. Seek comment from the CPAN maintainer and others.

Thank you very much.
