[Bug-gv] Compilation problems for GV 3.8.0

[Bert Deknuydt]

Hello,

Some problems compiling gv 3.8.0 with gcc 3.4.3.

--> On 64-bit platforms (e.g. x86_64) , there are plenty of 

    FileSel.c:1093: warning: cast to pointer from integer of different size

    in several files.  All in all it compiles and works, but this is
    somewhat 'fishy'.

--> On non-linux (e.g. Solaris 2.8, but also on Tru64 and HPPA and SGI),
    the compilation fails at:

main.c:145: error: elements of array `GNU_longOptions' have incomplete type
main.c:147: warning: excess elements in struct initializer
main.c:147: warning: (near initialization for `GNU_longOptions[0]')
main.c:147: error: `no_argument' undeclared here (not in a function)
main.c:147: warning: excess elements in struct initializer
main.c:147: warning: (near initialization for `GNU_longOptions[0]')
main.c:147: warning: excess elements in struct initializer
main.c:147: warning: (near initialization for `GNU_longOptions[0]')
main.c:147: warning: excess elements in struct initializer
main.c:147: warning: (near initialization for `GNU_longOptions[0]')
main.c:148: warning: excess elements in struct initializer

Greetings, Bert.
