+If you make changes to uconfig.sh, run
+
+ make -f Makefile.micro regen_uconfig
+
+to regenerate uconfig.h. (or regen_uconfig64 if you're editing uconfig64.sh)
+
+
+If neither of the above default configs work on your platform, you might want
+to try
+
+ make -f Makefile.micro patch_uconfig
+
+*before* the "make -f Makefile.micro". This tries to minimally patch
+the uconfig.sh using your *current* Perl so that your microperl has
+the correct basic types and sizes and byteorder.
