You're wrong :) #if is valid, but it expects a valid expression after
it - and if for example HAVE_TCGETATTR is not defined, it's
#if HAVE_TERMIOS_H &&
which sure looks like being capable of causing a parse error to me..

#if defined(HAVE_TERMIOS_H) && defined(HAVE_TCGETATTR)
But ofcourse you have to make sure that nobody does a
#define HAVE_TERMIOS_H 0 /* Nope, don't have it */
because then ofcourse HAVE_TERMIOS_H _would_ be defined anyway
and the above test would be correct after all..
But if this is autoconfed (sure looks like it) that is not the case,
HAVE_XXX is defined (as 1) or not defined at all.
