-###############################################################################
-#
-# Linking Mozilla itself to jemalloc is not particularly difficult.  To do this
-# we avoid linking directly to the Microsoft-provided CRT import libraries.
-# Instead, we link to our own import library which we generate here.  To
-# replace the CRT's malloc/free/other memory management symbols we export
-# our own versions out of jemalloc.dll.  We then take the import library that
-# the compiler generates for jemalloc.dll and combine it with the MS CRT import
-# libraries.  We put our library on the command line first, and the CRT symbols
-# are discarded in favor of our versions!
-#
-# Unfortunately that was too easy.  The CRT import library is not a standard
-# import library that contains a list of symbols and whatnot.  It also includes
-# object files that are linked into generated programs.  One of these,
-# crtdll.obj is (as one might expect) linked into all DLLs that link against
-# the CRT.  This file does things like run static C++ constructors when the
-# DLL is attached, call DllMain, etc.
-#
-# In the CRT source all malloc/free calls are made to malloc_crt and free_crt.
-# In debug builds these are both defined to malloc_dbg and free_dbg.  In opt
-# builds malloc_crt is an actual function, implemented and exposed from the
-# CRT.  free_crt is, however, defined to be just plain old free.  This works
-# fine inside the CRT where malloc_crt and free operate on the same heap.
-# Outside the CRT malloc_crt is in the CRT's heap, but free is in jemalloc's
-# heap.  This causes much pain at shutdown :-(
-#
-# The obvious solution here is to override malloc_crt too.  Unfortunately,
-# that doesn't work because the CRT expects to be able to call msize on this
-# piece of memory deep inside the CRT, which will fail because it'll call the
-# CRT's msize on a pointer in jemalloc's heap.
-#
-# Our solution to this is quite devious.  We take apart the CRT's import lib
-# and remove the problematic object file.  We then poke at the object file's
-# symbol table and replace '__imp__free' (which means grab free from some
-# other DLL) with '__imp__frex'.  Then we define our own dummy no-op function
-# in jemalloc.dll and export it as frex.  Then we put the CRT import lib
-# back together with the patched crtdll.obj, glue it to the end of jemalloc's
-# import library and link the rest of Mozilla to that.
-#
-# The result?  A binary that uses jemalloc, doesn't crash, and leaks a tiny
-# amount of memory (32 words per DLL in the 2010 CRT) at shutdown.
