! fixed va_start() use or, better, changed it to be compatible with OS/2 EMX GCC
compiler which REQUIRES that va_start() calls use a type which cannot be promoted
to something bigger. That is, this call is correct:
va_start(valist, ulUnsignedLongType)
while this one is not:
va_start(valist, usUnsignedShortType)
Using a type which can be promoted to a bigger one leads to memory corruption.
I think this requirement could exist even on other ANSI C compilers.
! Removed workaround inside hb_itemDo() and hb_itemDoC() to prevent this corruption.
