That's a silly warning, but doesn't seem to be the hint for the cause of 
trouble.  You can set "PICFLAGS=" for the two win32 targets in 
lib/Makefile to get rid of the warning.  I don't think it would change 
anything, though.  Has that win32 with mingw64 combination ever worked for 
you (with same configure and environment)?

alloca86.S is a 32bit assembler source, but you may have 
compiled it into a 64bit ELF file (when using gccs default options without 
-m32).  That would cause this error if tiny_libmaker is compiled with 
-DTCC_TARGET_I386 (as it seems it is above).  You probably want to add 
some -m32 somewhere in lib/Makefile for this combination.


Ciao,
