At a guess, judging from the CRLF line endings in the first 3 lines,
you're trying to build Cygwin on a text mount.  Thus, ld expects to see
all lines ending in CRLF.  However, gcc seems to write the defs with LFs
explicitly, so ld sees line 4 as one long line, and gives a parse error.
I'd suggest moving the build to a binary mount and trying again.

Doesn't Cygwin use Doug Lea's malloc?  I thought it had some leak
detection routines (or, at least, routines to print memory stats).  Take a
look at winsup/cygwin/malloc.cc...
