Move the _LARGEFILE64_SOURCE macro definition from individual source
files to CMakeLists.txt. This eliminates redefinition warnings when
system headers (features.h) also define this macro:
In file included from
/builddir/build/BUILD/multitail-7.1.5-build/multitail-7.1.5/mt.c:50:
/builddir/build/BUILD/multitail-7.1.5-build/multitail-7.1.5/mt.h:4:9:
warning: ‘_LARGEFILE64_SOURCE’ redefined
4 | #define _LARGEFILE64_SOURCE /* required for GLIBC to enable
stat64 and friends */
| ^~~~~~~~~~~~~~~~~~~
In file included from /usr/include/ctype.h:25,
from
/builddir/build/BUILD/multitail-7.1.5-build/multitail-7.1.5/mt.c:3:
/usr/include/features.h:238:10: note: this is the location of the
previous definition
238 | # define _LARGEFILE64_SOURCE 1
