Gnu software makes extensive use of alloca(). On the RT with hc2.1 there
is a builtin function called "_Alloca" which does what alloca() does (but
improves code quality, as the optimizer is free to fully optimize those
functions which do not use alloca, and a function call is not required in
those which do). The emacs machine dependent config file should be
changed to have these lines:
#ifdef __HIGHC__
#define alloca _Alloca
#endif
and the "-ma" compiler flag should be deleted.
