Here's my stab at an example, at least for i386 floppy (although
presumably the others might be made to work in a similar fashion?), as
this seems to be a FAQ:

In heaps.hxx:


Tacked on to the *end* of mlt_i386_pc_floppy.h:

#ifndef __ASSEMBLER__
extern char CYG_LABEL_NAME (__heap2) [];
#define CYGMEM_SECTION_heap2 (CYG_LABEL_NAME (__heap2))
#define CYGMEM_SECTION_heap2_SIZE (0xa00000)
                                   ^^^^^^^^ insert whatever here

The end of mlt_i386_pc_floppy.ldi:

    CYG_LABEL_DEFN(__heap1) = ALIGN (0x8);
    CYG_LABEL_DEFN(__heap2) = ALIGN (0x8);

Those seemed to do the trick for me!
