Linking split-objs fails with "xargs: /mingw/bin/ar: Bad file number"

[guest]

link-splitobjs.sh fails with the error "xargs: /mingw/bin/ar: Bad file number". It seems that the MinGW ar can only handle a limited number of objects at a time, and getting several hundreds at once causes it to error in such a way.

This is simple to fix, just change the line in link-splitobjs.sh.in:

cat ${lib}.list | xargs @AR@ q ${lib}

To:

cat ${lib}.list | xargs --max-args=100 @AR@ q ${lib}

I'm not sure if there's a way of finding out the maximum number that can be given easily, 100 worked fine. ar --version is GNU ar (GNU Binutils) 2.18.50.20080109 in case that makes a difference.

Relevant make output:

Linking libHSglib.a, for larger libs this can take quite some time...

If you do the job badly enough, sometimes you don't get asked to do it
