2019-03 (4.11.0) source file not found using cygwin [message #1805486]

I need a bit of help... and a fix/work around.

I'm attempting to create and build a default make project using the cygwin tool chain.

I get error on build:
Building in: C:\Users\xxxx\eclipse-workspace\test\build\make.debug.win32.x86_64
make -f ..\..\Makefile
g++.exe -c -g -o test.o /cygdrive/c/Users/xxxx/eclipse-workspace/test/test.cpp
g++.exe: error: /cygdrive/c/Users/xxxx/eclipse-workspace/test/test.cpp: No such file or directory
g++.exe: fatal error: no input files
compilation terminated.
make: *** [..\..\Makefile:19: test.o] Error 1
Build complete (1 errors, 0 warnings): C:\Users\xxxx\eclipse-workspace\test\build\make.debug.win32.x86_64

I've tried the old work around:
Window->Preferences->C/C++->Debug->Common source Lookup Path and add a path mapping that maps /cygdrive/<drive letter> to <drive letter>\:.
For example, > /cygdrive/c -> C\:.

That doesn't work..

Rather self-explanatory.

Window->Preferences->C/C++->Debug->Common source Lookup Path
You are getting the error from the compiler and not the debugger so debug preferences are irrelevant.

Are you running Eclipse in a cygwin terminal?
"Building in: C:\Users\xxxx\eclipse-workspace\test\build\make.debug.win32.x86_64" suggests otherwise.
cygwin maps the Windows C: drive to /cygdrive/c
Been a while since I've used cygwin but IIRC that mapping only works from a cygwin terminal.

This is quite embarrassing to say in a public forum...

The problem was a shadow copy of gnu tool chain was installed without notification with the Strawberry version of python for windows. Removing Strawberry's stuff from the path fixes the problem.
