    Hi,

    just tried this on solaris9/sparc:
    >-349: uname -a
    SunOS sb1001 5.9 Generic_112233-05 sun4u sparc SUNW,Sun-Blade-1000

    using:
    >-333: gcc -v
    Reading specs from /opt/nb/gcc-3.3/lib/gcc-lib/sparc-sun-solaris2/3.3/specs
    Configured with: ./configure --prefix=/opt/nb/gcc-3.3 --host=sparc-sun-solaris2 --enable-languages=c,c++,f77,objc,ada --enable-shared
    Thread model: posix
    gcc version 3.3

    >-339: cat gcc-muell.c
    int main(void)
    {
     printf("%c","msux"[0xcafebabe]);
    }

    >-340: gcc gcc-muell.c
    [Compiles w/o compaints!]

    >-341: ./a.out
     user=0.00 sec, sys=2.50 sec, elapsed=0:06.58 min, cpu use=37.9%
    [Runs w/o complaints!]

    >-342: truss ./a.out
    execve("a.out", 0xFFBFF8EC, 0xFFBFF8F4) argc = 1
    ...
    [...library mapping stuff...]
    ...
    getustack(0xFFBFF53C)
    getrlimit(RLIMIT_STACK, 0xFFBFF534) = 0
    getcontext(0xFFBFF370)
    setustack(0x7FB43944)
    ioctl(1, TCGETA, 0xFFBFEA04) = 0
    fstat64(1, 0xFFBFE920) = 0
    write(1, "\0", 1) = 1
    _exit(2141995056)
     user=0.04 sec, sys=2.40 sec, elapsed=0:06.28 min, cpu use=38.8%

    allocates a large bunch af mem (top says ~750MB) and print's the byte
    it's told to print... nice, eh???

    Just for fun:
    >-345: /opt/.awaySUNWspro/bin/cc -V
    cc: Sun WorkShop 6 update 2 C 5.3 2001/05/15
    usage: cc [ options] files. Use 'cc -flags' for details
    >-346: /opt/.awaySUNWspro/bin/cc gcc-muell.c
    >-347: ./a.out
     user=0.00 sec, sys=2.41 sec, elapsed=0:05.17 min, cpu use=46.6%

    same as above...

    Just my 0.02 Euros,

    -kurt
