When compiling the DJGPP project (after altering the makefile to work with plain MinGW - I ended up only removing the unnecessary -L and -I declarations), I got a complaint from the assembler:
312: Error: symbol 'copyloop' is already defined
317: Error: symbol 'endcopy' is already defined
from file "as_callfunc_x86.cpp".
Solved it by replacing the repeated copyloop's & endcopy's in AT&T asm code with "copyloop2" and "endcopy2" ("copyloop1" and "endcopy1" were already used somewhere else).
I hope that this report will be useful and that the next release will compile under MinGW without problems.
