Hi,
I tried to build a fresh cygwin dll and recognized that the tool "bc" seems newly be
used in
a helper script named cygmagic. One can say, please install it, but another way could
be to
minimize the needed helper packages. So this is a note for doing the second.
I found the following line in src/winsup/cygwin/cygmagic
awk '{print "obase=16;\"0x\";", $1}' | bc
another possibility without "bc" seems to me like this
awk '{printf("0x%x",$1) }'
So if someone means, that this is a good note, please use it, otherwise forget it.
