If I build either option of the patch under MinGW, I get an error in the
grammar files related to the IGNORE reserved word.

$ (./configure --host=x86_64-w64-mingw32 --without-zlib && make  && make
check) > /dev/null

In file included from ../../../src/include/parser/gramparse.h:29:0,
                 from gram.y:59:
../../../src/include/parser/gram.h:207:6: error: expected identifier before
numeric constant

I don't get this problem on Linux.

The build chain seems to meet the specified minimum:

flex.exe 2.5.35
bison (GNU Bison) 2.4.2
This is perl, v5.8.8 built for msys-64int

It seems like IGNORE is getting replaced by the preprocessor with something
else, but I don't know how to get my hands on the intermediate file after
the preprocessor has done its thing.

Also, in both Linux and MinGW under option 1 patch I get an OID conflict on
OID 3261.

Cheers,
