  1. autoconf + newer gcc barfs

    Trond Eivind Glomsrød <teg@redhat.com> — 2002-01-23T17:48:42Z

    GCC CVS now outputs a multiline version string:
    
    [teg@halden teg]$ gcc --version
    gcc (GCC) 3.1 20020115 (Red Hat Linux Rawhide 3.1-0.18)

    [teg@halden teg]$ 
    
    It also complains about multiline literals being deprecated, like
    
    #define CC_VERSION "FOO
    
    BAR
    "
    
    Autoconf thinks these warnings (which it will get for pretty much all
    tests, as this is in confdefs.h) means the test failed.
    
    One way to work around this is:

    I put in a "head -1" step per your suggestion.  However, this will still
    leave us with really ugly version strings, along the line of
    
    PostgreSQL 7.2rc1 on hppa-hp-hpux10.20, compiled by GCC gcc (GCC) 3.1 20020115 (Red Hat Linux Rawhide 3.1-0.18)
    
    May I suggest that gcc is being a little too verbose here?  Perhaps
    "gcc --version --verbose" could do that, and plain "gcc --version"
    could try to have some respect for compatibility with prior behavior.
