This example works Ok for me with:
 	gcc-2.95 + binutils-2.9.1 + DJGPP CVS version (end of July)
	gcc-2.95.1 + binutils-990817 snapshot + DJGPP CVS version (16
                              August)
       gcc-2.95.1 + binutils-2.8.1(from Simtelnet) + djdev202 (unchanged)

In all cases no my additional changes to djgpp.djl

Kill  COMPILER_PATH  in DJGPP.ENV to workaround problem in old 
libc.a (You got ENFILE instead of ENMFILE). Problem is fixed long 
time ago and it should be fixed in last update of gcc-2.81 for DJGPP
(timestamp 22 October 98 perhaps)

Unfortunatelly CPP from gcc-2.95.1 doesn't seem to support -undef
