further gcc-15 fix for gmp on -std=23

Browse Source 
the fix in the previous revision wasn't being applied

a conftest.c file, and the entry being made for it was
actually coming from this place in the configure file.

+
+the previously merged revision was correct, but
+applied in the wrong place. the conftest.c file
+was being generated by configure, in this place.
+
+this should fix build errors now, on gcc-15.
