I'm still stumped on how to reproduce this; on latest gnulib.git
installed in a Cygwin setup, I did:
./gnulib-tool --create-testdir --dir=testdir0 fseeko
then in that directory did a configure with a cross compiler:
./configure --host=i686-pc-mingw32 --build=i686-pc-cygwin
and the resulting build passed all tests. Looking in config.status, I see:
S["REPLACE_FSEEKO"]="0"
S["REPLACE_FSEEK"]="1"
S["HAVE_FSEEKO"]="0"
S["HAVE_DECL_FSEEKO"]="0"
which differs from your setup. Maybe I should repeat my tests with
mingw64 instead of the older mingw32?
