Actually I was just checking the so copied config.h when I thought it
might be a good idea first to check out the config.h computed by
address@hidden, hence I decided first to run the 'default'
build procedure, with cygwin and with msys/mingw.

E.g. I hoped that address@hidden would suggest
'#define FILE_TIMESTAMP_HI_RES 1' (-> turned out not).
Also for other defines I'm interested in the config.h produced by

Another reason for me to preferre buliding via address@hidden:
I probably have to use the resulting gmake together with msys' sh.exe
to get working "gmake -j" (dual core :-) ... I guess the optimal
partner of msys' sh.exe is gmake built via address@hidden

("gmake -j": I still dont know whether '#3678 make -j unnecessarily
requires an Unix shell' 
will work for current gmake, built with build_w32.bat ...)

Btw, despite the trailing error, address@hidden DID result
in a working make.exe; nevertheless I'd like to know whether others
can reproduce (or better: help me solve) that error.

Btw 2, many thanks to you, JGrant, Paul and colleagues for putting
so much efforts in gnumake381's builtin windows support !
