Shell invocation flags

[Dan Oelke]

I have make 3.80 from a recent cygwin update.  I am attempting to create 
a Visual Studio project that will invoke this make and from there on I 
can update a (reasonable) makefile instead of a Visual Studio project. 

My problem is that when I invoke make from a bash shell everything is 
ok.  When it's invoked from inside the bowels of Visual Studio I get an 
error:
   ./Components/CygwinTools/Utils/bash: /c: No such file or directory

My makefile has SHELL defined as:
   SHELL := ../Components/CygwinTools/Utils/bash

When I invoke make from the normal bash shell I have all the unix 
variables, etc.  When it's invoked from inside of Visual Studio I just 
have the few things I've checked into our source control system.  
(bash.exe, make.exe, cygwin1.dll, etc)

So it appears that make is adding -c when it thinks its in a normal Unix 
environment and /c when it thinks it's in a DOS type environment.  That 
make sense.  But - how do I tell make that I'm in a Unix environment and 
using cygwin tools?

Thanks,
Dan
