/proc/cpuinfo output differs from Linux

[Diego Biurrun]

Hello!

I am an MPlayer developer and was wondering why our configure script was 
suddenly failing to detect my K6-III CPU.  Then I noticed that Cygwin 
/proc/cpuinfo formatting is not the same as in Linux.

Cygwin:
   $ cat /proc/cpuinfo
   vendor id       : AuthenticAMD

Linux:
   lea:~$ cat /proc/cpuinfo
   vendor_id       : GenuineIntel

Cygwin outputs "vendor id" (with a blank), while Linux uses "vendor_id" 
with an underscore.  We use this information to identify processors and 
set up optimizations accordingly.

I grepped through the Cygwin sources for "vendor id" and made a small 
patch.  It is not tested but trivial, so I expect it to be fully correct.
Regards
