+    Revert "x86 (32bit): force -mpc64 on compilers that supports it."
+    
+    This reverts commit ca61b6391cf95ac8af15669236e2ec5839d2ad91.
+
+
+This causes problems with floating point precision on i686:
+```
+$ cat exp40.c
+#include <math.h>
+#include <stdio.h>
+int main() {
+	volatile int a=40; /* do not optimize away the call to exp(a) */
+	printf("%f\n", exp(a));
+}
+$ cc -Wall exp40.c -lm && ./a.out
+235385266837020000.000000
+$ cc -Wall exp40.c -lm -mpc64 && ./a.out
+235385266837020448.000000
+```
+
+Note that when pari is built using -mpc64, just *linking* with -lpari
+causes the problem!!!
+```
+$ cc -Wall exp40.c -lm -lpari && ./a.out
+235385266837020448.000000
+```
