I can't reproduce this on Solaris 8, SPARC, with gcc 3.4.1. Here's line
2558:
bof = PerlIO_tell(PL_rsfp) == (Off_t)SvCUR(PL_linestr);
It's possible your gcc would be happier with an extra pair of parentheses
around the righthand side of the '=' sign.
You can also try
make toke.i
to see what that line expands to for your system. For me, it gave
bof = Perl_PerlIO_tell(PL_rsfp) == (off64_t)((XPV*)
(PL_linestr)->sv_any)->xpv_cur;
which looks fine.
If you suspect your compiler, you can tell it not to optimize (toke.c is
the most tortuous file to optimize) with
rm toke.o
make toke.o OPTIMIZE=
to turn off the optimizer for that file.
For comparison, here's the output of my ./myconfig:
