I attained the following output from the attached patch:

      7 [main] ? (4876) heap_init: baseAddr:  0x680000
    171 [main] ? (4876) heap_init: allocBase: 0x670000
    347 [main] ? (4876) heap_init: allocProt: 0x20
    425 [main] ? (4876) heap_init: regionSize:0xA7000
    502 [main] ? (4876) heap_init: state:     0x1000
    614 [main] ? (4876) heap_init: protect:   0x20
    693 [main] ? (4876) heap_init: type:      0x40000
    778 [main] ? (4876) C:\cygwin\bin\make.exe: *** fatal error - couldn't allocate heap, Win32 error 487, base 0x680000, top 0x6B0000, reserve_size 192512, allocsize 196608, page_const 4096

I know this isn't much to go on, but just in case...

I really wish I had more than a few minutes a week to spend on this :-(.
Perhaps then I'll be able to figure it out.

You don't have any suggestions for how to best separate the patch into
pieces do you?
