When generating the makefile, make sure that the paths are quoted so
that a native Windows path works within Cygwin.
Without this patch, this error is reported by the DejaGNU test suite:
make: [T:\ccMf0kI3.mk:3: T:\ccGEvdDp.ltrans0.ltrans.o] Error 1 (ignored)
The generated makefile fragment without the patch:
T:\ccGEvdDp.ltrans0.ltrans.o:
@T:\build\bin\arm-none-eabi-g++.exe '-xlto' ... '-o'
'T:\ccGEvdDp.ltrans0.ltrans.o' 'T:\ccGEvdDp.ltrans0.o'
@-touch -r T:\ccGEvdDp.ltrans0.o T:\ccGEvdDp.ltrans0.o.tem > /dev/null 2>&1
&& mv T:\ccGEvdDp.ltrans0.o.tem T:\ccGEvdDp.ltrans0.o
.PHONY: all
all: \
T:\ccGEvdDp.ltrans0.ltrans.o
With the patch, the touch line would be replace with:
@-touch -r "T:\ccGEvdDp.ltrans0.o" "T:\ccGEvdDp.ltrans0.o.tem" > /dev/null
2>&1 && mv "T:\ccGEvdDp.ltrans0.o.tem" "T:\ccGEvdDp.ltrans0.o"
