Hi, Here are test results of the today's gzip git + newest gnulib (= nearly the same as Jim's gzip-1.8.40). I tested only 32-bit platforms. 1) On Linux/i386 (on a bi-arch system): Linux/hppa (on a Linux/x86_64 system): Linux/m68k (on a Linux/x86_64 system): Linux/arm (on a bi-arch system): Linux/powerpc (on a bi-arch system): Linux/s390 (on a bi-arch system): AIX/powerpc (on a bi-arch system): - By default: configure: error: This package requires a 64-bit 'time_t' type, which your system appears to support. You might try configuring with 'CPPFLAGS="-m64" LDFLAGS="-m64"'. To build with a 32-bit time_t anyway (not recommended), configure with 'TIME_T_32_BIT_OK=yes'. - With TIME_T_32_BIT_OK=yes: FAIL: timestamp 2) On Linux/x86_64-x32 (on a bi-arch system): Linux/mips o32: Linux/mips o32 (on a bi-arch system): Linux/mips n32 (on a bi-arch system): Linux/arm: Hurd/i386: NetBSD/i386: Solaris 10/i386 (on a bi-arch system): Solaris 10/sparc (on a bi-arch system): Mac OS X/i386 (on a bi-arch system): Mac OS X/powerpc (on an x86_64 system): All tests pass. 3) Linux/sparc (on a bi-arch system): On some machines, like 1). On other machines, like 2). 4) FreeBSD/i386: Haiku/i386: HP-UX/hppa: HP-UX/ia64: The timestamp test passes, but some other tests fail (see separate mail). 5) OpenBSD/i386: NetBSD/sparc: IRIX n32: FAIL: timestamp Find attached the test-suite.log of each platform.
