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. Leo
