It didn't help.  It looks because, under certain circumstances, perl.h
defines PERL_IMPLICIT_CONTEXT.

This command does succeed (but fails to link due to vasprintf):

  $ make PERL_INC=/d/usr/Perl/lib/CORE LDFLAGS='-no-undefined 
-L/d/usr/Perl/lib/CORE -lperl520' PERL_CONF_ccflags='-DPERL_TEXTMODE_SCRIPTS 
-DUSE_SITECUSTOMIZE -DUSE_PERLIO'

But removing flags emitted by fetch_conf.pl, just because they cause
compilation errors, sounds dubious, no?
