"make check" failure when building GNU m4 1.4.13 on Mac OS X Snow Leopard

[Leo Davis]

Hello,

I tried building GNU m4 1.4.13 on a MacBook running Snow Leopard (10.6.1
Intel).
I have Xcode 3.2.1 installed (gcc is i686-apple-darwin10-gcc-4.2.1 (GCC)
4.2.1 (Apple Inc. build 5646) (dot 1) according to config.log).

The "make check" failure I'm seeing is:

test-strtod.c:647: assertion failed
test-strtod.c:648: assertion failed
FAIL: test-strtod

this corresponds to the source lines:

    ASSERT (ptr1 == input + 4);         /* OpenBSD 4.0, HP-UX 11.11,
IRIX 6.5, OSF/1 5.1, Solaris 2.5.1, mingw */
    ASSERT (ptr2 == input + 4);         /* OpenBSD 4.0, HP-UX 11.11,
IRIX 6.5, OSF/1 5.1, Solaris 2.5.1, mingw */

in a block that starts with:

    const char input[] = "+nan(";


I previously had Leopard installed on this computer with an earlier
version of Xcode and built GNU m4 1.4.11.  I'm pretty sure I
successfully ran "make check" before I installed it.  I decided to try
and build GNU m4 1.4.11 and got the same test failure.
