Q37901: "Duplicate Definition" LINKing C Graphics Library to BASIC, /O

The C graphics library, GRAPHICS.LIB, is incompatible with programs
compiled with BC /O in QuickBASIC versions 4.00, 4.00b, and 4.50,
Microsoft BASIC Compiler versions 6.00 or 6.00b, or Microsoft BASIC
Professional Development System (PDS) version 7.00. The FONT and CHART
graphics in QuickC version 2.00 are also incompatible with programs
compiled with BC /O in these versions of QuickBASIC and BASIC
compiler. Many of the C graphics routines conflict with the BASIC
graphic routines in the BASIC stand-alone library. If you need to do
graphics when you link BASIC stand-alone programs with C, the graphics
should be done in BASIC. An alternative is to compile without the BC
/O option in BASIC.

Linking BASIC programs compiled BC /O with Microsoft C graphics
routines gives many "Duplicate Definition" errors, even if you LINK
with the /NOE option. Compile without /O to eliminate the errors.
