I just happened to redirect stdout to /dev/null while building wx with a
hacked version of lmi's makefile, so I thought I'd report the messages here.
There are no actual problems; I'm just curious about a few things.

/home/greg/src/lmi[0]$time make $coefficiency -f install_wx.make >/dev/null
/bin/sh: 1: cd: can't cd to samples
make[1]: [clean] Error 2 (ignored)
/bin/sh: 1: cd: can't cd to samples
make[1]: [distclean] Error 2 (ignored)
make: [all] Error 1 (ignored)

That's from the clean targets; it may not be worth doing anything to
suppress such messages.

configure: WARNING: type_traits: accepted by the compiler, rejected by the 
configure: WARNING: type_traits: proceeding with the compiler's result

There's that weirdness again.

configure: WARNING: Defaulting to the builtin regex library for Unicode build.
configure: WARNING: zlib library not found or too old, will use built-in instead
configure: WARNING: system png library not found or too old, will use built-in 
configure: WARNING: system expat library not found, will use built-in instead

Here, the only thing I think remarkable is that MinGW-w64 provides zlib,
and it's...too old? But...
  "MinGW-w64 4.9.1 comes with zlib 1.2.8"
and that's the current release according to
Or is it not found because it's in some compiler subdirectory instead
of a canonical location?

configure: WARNING: Assuming Unix98 printf() is not available,
define HAVE_UNIX98_PRINTF as 1 in setup.h if it is available.

I guess this means extensions like the '$' here:
  printf("%2$*1$d", width, num);
that are SUSv2 but not C99.

configure: WARNING: Catching fatal exceptions not currently supported on this 
system, wxApp::OnFatalException will not be called

No SEH; that's understood.

config.status: WARNING:  '../../../src/expat/Makefile.in' seems to ignore the 
--datarootdir setting

I don't recall seeing that warning in prior years.
