I too have had some problems building jdk7 on cygwin.   I believe they are caused by

I am in the process of submitting a CR with my findings.

FWIW, my workarounds are in jdk file Defs-windows.gmk:
1.   makefile assumes cygwin is at c:/cygwin which isn't true for me.  Workaround is:

2  $(call MixedPath,/cygdrive/j) returns empty .  Workaround is:
> define FullPath
> $(shell $(CYGPATH_CMD) $1 2> $(DEV_NULL))
> endef 

3.  I was setting ALT_UNIXCOMMAND_PATH to /usr/bin and had to change it to /bin
  This could have been a side effect of the first three issues.

I don't know if these workarounds would work for you or not.
