Thanks.

I believe I've tried that before and now did again with just the version
file fix: no dice.
And no, this is the first time ever that I had such an issue.

After the fresh built, among others with
/vol/gcc/src/hg/master/local/libgfortran/ieee/ieee_exceptions.F90:28:2:

Fatal Error: kinds.inc: No such file or directory
I compared make --debug=verbose for that file and bounds.lo: one glaring
difference is that for bounds.lo the debug output lists
Considering target file 'bounds.lo'.
File 'bounds.lo' does not exist.

Must remake target 'ieee_exceptions.lo'.
i.e. it lists no prerequisites beside the source itself. The bounds.lo
prerequisites are both from the Makefile proper and .deps/bounds.Plo
while .deps/ieee_exceptions.Plo doesn't exist/isn't generated.
The compile command for bounds.lo includes -MF $(DEPDIR)/bounds.Tpo has
nothing of the kind. No idea why. Maybe a difference between C and
Fortran sources in Automake?
