#3650 open defect

configure fails for VS2013 if environment variable 'CL' was set

Summary of the bug:

Certain values for the environment variable 'CL' on Windows break MSVC-based builds.

How to reproduce:

Set CL to '/MP' (or similar arguments containing forward slashes)

On several occasions (configure and actual build) msys path conversion kicks in and mangles the environment variable into something like 'c:\mingw\msys\1.0\MP', leading to missing bogus files for compiler and linker.


set 'CL' to '-MP' or similar. The error is not ffmpegs fault but hard to identify, and should at least be mentioned at documentation level:
