I keep Emacs up to date on both GNU/Linux and Windows machines.
Installing the GNU/Linux from source was trivial, as would be expected.
However, compiling the Windows version from source gave me the following
error (at end of email). To work around this quite annoying error, I had
to manually edit malloc.h in MinGW/include and have it forcibly define
alloca and _alloca as __builtin_alloca. When I do this, things all
compile fine and I have a brand-spanking new Emacs 24.4 on my Windows
machine that runs as well as my 24.3 build from last year.
My point: It really, REALLY doesn't feel nice to edit malloc.h!
My question: What am I doing wrong that requires me to do this? And if
this is required, shouldn't a pointer to doing this be in the INSTALL
file in the nt subdirectory?
Thanks for any thoughts,
Joel

You shouldn't need to. There's some snafu at work here, see below.

I don't understand how this happened. src/conf_post.h around line 49
says:
#ifndef WINDOWSNT
/* On AIX 3 this must be included before any other include file. */
#include <alloca.h>
#if ! HAVE_ALLOCA
# error "alloca not available on this machine"
#endif
#endif
So this fragment, including the #error directive, should not be
compiled on Windows, unless WINDOWSNT is not defined in your build.
WINDOWSNT is defined by src/config.h:
/* Define if compiling for native MS Windows. */
#define WINDOWSNT 1
which happens because of this snippet in the configure script:
case $opsys in
[...]
mingw32)
$as_echo "#define DOS_NT /**/" >>confdefs.h
$as_echo "#define WINDOWSNT 1" >>confdefs.h
So if your configuration was recognized as "mingw32" (and it was,
according to the summary displayed by the configure script), which
means opsys was set to mingw32, how come WINDOWSNT is not defined?
Can you look into config.log and config.h and figure out what went
wrong there?
