Fix LFS with -Duseperlio in Solaris.  Reported in
To: perl5-porters@perl.org
Subject: [ID 19990823.009] [PATCH perl5.005_61] typo in perl.h
Message-Id: <199908231541.QAA10043@tempest.npl.co.uk>

and later (in private email) found to be dependent
on useperlio.

Mental note: the cpp magic done in perlsdio.h (and assumedly
also in perlsfio.h) may cause trouble later with lfs because
both the perlio scheme by Perl and the lfs support by vendors
like to play cpp games to map the stdio namespace back and forth.
The problem fixed here (fseek vs fseeko, ftell vs ftello) may be
just the beginning.
