R: [Linrad] Linrad-02.53

["libero.it; ik7ezn@xxxxxxxxxxxxxxxx>]

Hi Leif.

I found that with the new version of gcc ships with the Ubuntu 8.10 
xlinrad not compile with the following error:

gcc version 4.3.2 (Ubuntu 4.3.2-
1ubuntu11) 
root@xxxx:~# cd /usr
root@xxxx:/usr# cd linrad-02.53
root@xxxx:
/usr/linrad-02.53# make xlinrad
gcc xmain.c -g -O -DOSNUM=1 -W -Wimplicit -
Wreturn-type -Wformat -m32 -Wunused -Wcomment -Wchar-subscripts -Wshadow -
Wuninitialized -Wparentheses -Wstrict-prototypes -Werror -ffast-math -fomit-
frame-pointer -c -o xmain.ol
cc1: warnings being treated as errors
xmain.c: In 
function âui_setupâ:
xmain.c:597: error: ignoring return value of âfgetsâ, 
declared with attribute warn_unused_result
make: *** [xmain.ol] Error 1


I 
installed the old version GCC-3.4 and all working fine.
