x64 perl-5.24.0 built using gcc-5.3.0

[sisy...@optusnet.com.au]

Hi,

I generally build perl myself (using a mingw-w64 port of gcc).

With these perls (both 32-bit and 64-bit) when I build a perl extension, the
extension's dll that gets built has always been dependent on
libgcc_s_sjlj-1.dll .... until 64-bit gcc-5.3.0.

With the 32-bit perl-5.24.0 (built with 32-bit gcc-5.3.0) the
libgcc_s_sjlj-1.dll dependency is still there, but not with 64-bit
perl-5.24.0 (built with 64-bit gcc-5.3.0).

For example, with the 32-bit gcc-5.3.0:

C:\>objdump -x C:\MinGW\perl524_64int_ld\site\lib\auto\Math\GMPz\GMPz.dll |
grep "DLL Name"
DLL Name: libgcc_s_sjlj-1.dll
DLL Name: msvcrt.dll
DLL Name: KERNEL32.dll
DLL Name: perl524.dll

And with the 64-bit gcc-5.3.0:

C:\>objdump -x C:\_64\perl524_530_ld\site\lib\auto\Math\GMPz\GMPz.dll | grep
"DLL Name"
DLL Name: msvcrt.dll
DLL Name: KERNEL32.dll
DLL Name: perl524.dll

Does anyone know why this behaviour might be different for the 64-bit
gcc-5.3.0 ?
Has anyone else seen this behaviour ?

Here's the gcc -v output:
