REMOVE THIS BUG REPORT, IT WAS A USER ERROR! Sorry!

The following error occurs when attempting to compile MariaDB C Connector with an included Fltk lib (Just recompiled fltk-1.3.3 to confirm it wasn't a bad copy).

What I am typing in Mingw64 shell (part of Msys2):
g++ -o ./test.exe -I'../MariaDB Connector C 64-bit/include' -I/usr/local/fltk-1.3.3/include -mwindows -L/usr/local/fltk-1.3.3/lib '../MariaDB Connector C 64-bit/lib/libmariadb.dll' /usr/local/fltk-1.3.3/lib/libfltk.a -lole32 -luuid -lcomctl32 ./cellstructures.cpp ./test.cpp

and

gcc -o ./test.exe -I'../MariaDB Connector C 64-bit/include' -I/usr/local/fltk-1.3.3/include -mwindows -L/usr/local/fltk-1.3.3/lib '../MariaDB Connector C 64-bit/lib/libmariadb.dll' /usr/local/fltk-1.3.3/lib/libfltk.a -lole32 -luuid -lcomctl32 ./cellstructures.cpp ./test.cpp

Which results in these errors

C:\Users****\msys64\tmp\ccj6bAyV.o:cellstructures.cpp.rdata$.refptr.FL_NORMAL_SIZE[.refptr.FL_NORMAL_SIZE]+0x0): undefined reference to `FL_NORMAL_SIZE'
