I should have stated that I used -2147483647 just to see if it would get
passed the current roadblock, not as a permanent solution. But I did
recompile with -2147483647-1 and it also finishes building. 3 test
scripts still fail:
pragma/warnings.......PROG:
# pp_hot.c [pp_print]
use warnings 'io' ;
print STDIN "anc";
print <STDOUT>;
print <STDERR>;
open(FOO, ">&STDOUT") and print <FOO>;
print getc(STDERR);
print getc(FOO);

# The next test is known to fail on some systems (Linux+old glibc, #

#read(FOO,$_,1);
no warnings 'io' ;
print STDIN "anc";
