-Fnoboundchecks is now -Fno-boundchecks (actually inverted behaviour with default-to-on) because -Fno-noboundchecks was stupid. bound checks are disabled when trying to compile xonotic (because xonotic is buggy and accesses arrays out of bounds).
fix logicops following vector types to shortcircuit properly. fix ternary operators ending in field references - no longer ignores the result of the true pathway. these two fixes appear to be sufficient to compile xonotic (note the array bounds issues that are abundant in xonotic, which will break with -TFTE and its direct array indexing, so be sure to re-enable bounds checks). The result probably isn't perfect, but it seems to work for me. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5162 fc73d0e0-1445-4013-8a0c-d673dee63da5
