[7u]: help on jdk/make/common/shared/Defs-windows.gmk

[Erik Joelsson]

The way I understand it $(if $(word 2,$1) is a check for whitespace in 
the input parameter. It's an optimization to avoid executing cygpath 
when it's not needed. The MixedPath macro cannot be used if the path 
contains a space. It also doesn't convert to an absolute path, just 
replacing cygwin specific paths with driveletter paths. The unfortunate 
effect of this is that FullPath behaves differently depending on if the 
path contains a space.

How are you invoking the build to cause this error? Are you explicitly 
setting ALT_OUTPUTDIR? What is the path to your workspace?
