Log: Fix uninitialized warning, and work around a bug in gcc over clobbering Summary: r329077 caused gcc to emit uninitialized use warnings. Attempting to fix those warnings yielded the following warnings: usr.bin/tftp/main.c: In function 'main': usr.bin/tftp/main.c:181: warning: variable 'el' might be clobbered by 'longjmp' or 'vfork' usr.bin/tftp/main.c:182: warning: variable 'hist' might be clobbered by 'longjmp' or 'vfork' This is a known bug in gcc, found at https://gcc.gnu.org/bugzilla/show_bug.cgi?id=24239 Work around that by simply marking hist and el as static.
