FW: Fix for B20 make bug

["Hugh Winkler" <hughw at scoutsys dot com>]

Hi all,

This patch repairs  the file ./src/make/read.c in cygwin b20 source
distribution, fixing bug where you couldn't have multiple targets beginning
with '/'.

Snip the patch below into a file named say ./src/make/patchfile. Save a copy
of read.c if you want. Then
  cd ./src/make
  patch read.c patchfile
and run make.

Course you could just get the repaired binary
ftp://ftp.scoutsys.com/su/cygwin/make.exe.bz2

Maintainer please remove my comment after checking it. I suspect the check,
  stopchar == ':',
is only there due to cut and paste from other code in the file, and what
really is needed is just to see whether
  p[0] == ':'.

But I left the stopchar comparison in anyway.
