FYI: In general, you need (and always needed) a C compiler
to build PAR::Packer. But failing that "perl Makefile.PL" tries
to find a pre-built PAR::Packer on CPAN that matches your installation.
In the past you just got lucky that it found one.

The last line explains what your seeing: boot.exe is linked against
libgcc_s_dw2-1.dll and hence needs it to be present in PATH
to run. Same goes for all pp'ed executables because they basically
consist of boot.exe concatenated with a PAR file.
AFAICT there is no need to link boot.exe against libgcc_*.dll.
Looking at your build log, the most likely suspect is this line:
C:\MinGW\bin\g++.exe boot.o ... -o boot.exe
i.e. using g++ as linker (instead of gcc). That will probably include
support for exception handling which pulls in libgcc.
Now "C:\MinGW\bin\g++.exe" is just Config{ld} from your Config.pm.
Hmm... I understand why ActiveState wants to link "as C++" and that's
correct for linking par.exe (which is a special-purpose Perl
interpreter), but unfortunately not for boot.exe (which is a standalone
executable that has nothing to do with Perl).
Please try the patch below (on top of the previous patch)
and check if it makes the reference to libgcc*.dll in boot.exe
go away.
