I don't think you mean to change the size of the cygheap to 1792 Megs,
do you?  This sounds impossible to me.  Keep in mind that you only have
2 Gigs total memory available per application.

The cygheap size is usually 1 MByte, + the number of pages to align the
end of the cygheap section to the next 64K boundary.  In a case like
this you can increase the cygheap to, say, 2 Megs + alignment, but that
should be enough for all cases which fit into memory at all.

Otherwise, ld should use temporary files to store intermediate data.
