Weird compiling error - windoze+backslashes?

[Nobody/Anonymous]

Something really weird is happening - dev-cpp has been working fine for ages, and now (after firing it up for the first time in a few weeks) it does this - for any project (I just created a simple default "hello world" project)  - anyone seen this before???

It seems to be losing the backslashes in the g++ path... so I tried changing it to double backslashes for the g++ path *only*, and this is what it does:

Any clues?  I'm completely baffled.

I just noticed it was picking up some path info from another installation in c:\dev-cpp - have fixed all my paths now - it didn't fix my problem though....

BUT....

I put the path to g++ in quotes (i.e. "d:\dev-cpp\bin\g++.exe") and it works!(?)

Crazy stuff...
