Just a guess, but in your perl -V, you have

To compare, with my Win32 ActivePerl, perl -V:ccflags is

ccflags='-nologo -GF -W3 -MD -Zi -DNDEBUG -O1 -DWIN32 
-D_CONSOLE -DNO_STRICT -DHAVE_DES_FCRYPT -DNO_HASH_SEED 
-DUSE_SITECUSTOMIZE -DPERL_IMPLICIT_CONTEXT
-DPERL_IMPLICIT_SYS -DUSE_PERLIO -DPERL_MSVCRT_READFIX'

along with

  Compile-time options: MULTIPLICITY PERL_IMPLICIT_CONTEXT
                        PERL_IMPLICIT_SYS PERL_MALLOC_WRAP
                        PL_OP_SLAB_ALLOC USE_ITHREADS
                        USE_LARGE_FILES
                        USE_PERLIO USE_SITECUSTOMIZE

What I'm wondering is why your perl -V:ccflags doesn't
include -DPERL_IMPLICIT_CONTEXT, etc.? Assuming the
same compile time options were used, is it possible
to compare perl -V:ccflags with that of the binary
perl that you used successfully to build mod_perl?
