Nobody here is writing about running DJGPP under 64-bit WIndows directly

The problem is with compiling sources for DJGPP using cross-compiler on 64 bit and 32 bit systems 
(in this case Linux).
Cross-compilers built for 32- and 64-bit Linux versions produce slightly different output. I 
suspected (due to uninitialized
memory use errors detected by Valgrind) that repeatedly running compiler for same system could also
produce different results but failed to detect it on 64-bit Linux (Fedora 22 x86_64)

There seems to be no problems with DJGPP native compiler. Bootstrapping gcc is very sensitive about 
such problems so
all is perhaps OK with native compiler
