Subject: ; Avoid compiler warnings in the MS-Windows build
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=bdfd9865a5df8e43bbadb68fef215b776f12f025;p=emacs.git

; Avoid compiler warnings in the MS-Windows build

* src/w32heap.c: Remove unused variables, to avoid compilation
warnings.  This removes variables that were used only in the
unexec build.

(cherry picked from commit 22ab03e155adc4df0623e3ee9c2cc56a228e148a)

-   This point deserves an explanation.

-   The W32 heap allocator can be used for a growable heap or a
-   non-growable one.
-
-   A growable heap is not compatible with a fixed base address for the
-   heap.  Only a non-growable one is.  One drawback of non-growable
-   heaps is that they can hold only objects smaller than a certain
-   size (the one defined below).  Most of the larger blocks are GC'ed
-   before dumping.  In any case, and to be safe, we implement a simple
-   first-fit allocation algorithm starting at the end of the
