GCC can't find its header directoriescy

["Duncan Roe" <droe at mintec dot com dot au>]

Thanks guys for the pointers to cygmpfr-4.dll. Got it.

This problem with headers started happening on an old installation so I
reinstalled but it still happens:

/usr/include definitely exists but gcc / cpp claims it does not.
Since this "just started happening" I wonder whether it is caused by
some update to Windows. (Win XP SP3).

Anyone else seen anything like it? I'm stuck,

Cheers ... Duncan.
