mingw32 + libgomp

[Daniel Franke]

Hi all.

Using 4.2 sources, I now have a i686-pc-mingw32 linux-to-windows 
cross-compiler up and running. Unfortunately, building an OpenMP enabled 
program (-fopenmp) fails with

> libgomp.spec: No such file or directory


I assumed libgomp for OpenMP enabled programs would be available for this 
configuration, but:

Could someone elaborate on what's missing to get libgomp for a target-mingw32 
cross-compiler? 

Thanks

P.S. In PR30546 FX states "mainline now fails to build on my mingw setup 
because libgomp wants to run makeinfo" which indicates that there is some way 
to get libgomp running on mingw32?!
