Subject: Promote varargs pointers to RESULT_TYPE_GPTR
X-Git-Url: https://git.gag.com/?p=fw%2Fsdcc;a=commitdiff_plain;h=a38f33ebea19e30a1adc71fb457b4002c4c3c787

Promote varargs pointers to RESULT_TYPE_GPTR

The addition of the RESULT_TYPE_GPTR as distinct from RESULT_TYPE_NONE
was not propogated into the varargs function parameter handling code
resulting in non-generic pointers being passed to varargs functions.
