    PR modula2/110174 Bugfixes to M2GenGCC.mod:CodeInline preventing an ICE

    This patch calls skip_const_decl before chaining parameter values and
    ensures that all strings passed to build_stmt (..., ASM_EXPR, ...) are
    nul terminated.  It also improves the accuracy of locations in
    function calls and asm statements.
