(fix of commit af00c4d)
* mark.c [!OS2] (GC_mark_from): Replace (signed_word)v>=0 to (v&SIGNB)==0
(anyway, the compiler generates the same code).
# ifdef OS2 /* Use untweaked version to circumvent compiler problem */
while ((word)mark_stack_top >= (word)mark_stack && credit >= 0)
# else
- while ((signed_word)(((word)mark_stack_top - (word)mark_stack)
- | (word)credit) >= 0)
+ while (((((word)mark_stack_top - (word)mark_stack) | (word)credit)
+ & SIGNB) == 0)
# endif
{
current_p = mark_stack_top -> mse_start;
