Hi all, hi Gerald, hi Tobias and Roman,

the patch updates gcc-5/changes.html; the Fortran bits are obvious.

For CLooG:
* That CLooG is no longer needed is the main reason for writing this
  Caveat item.

* Regarding ISL 0.12.2: The recommended version already changed
  2014-02-13 and thus for 4.9 (cf. PR59878); gcc-4.8/changes.html
  had 0.11.1 - and gcc-4.9/changes.html doesn't mention ISL or CLooG.
  I don't know whether the GCC 5 change of using ISL directly instead
  of CLooG with ISL backend causes an explicit requirement of ISL 0.12.2,
  but not using 0.11.x is definitely a good idea.

* It is planned to additionally support ISL 0.14.0 (which fixes
  PR62289) - but which is API incompatile to ISL 0.12.2. Whence that
  patch is in, one has to re-write this item.

OK? Comments? Suggestions?

* * *

BTW: There is currently no version check in configure for ISL, maybe one
should add one for include/isl/stdint.h, which defines:
#define _GENERATED_STDINT_H "isl 0.12.2"
For the in-tree build, one could check isl/GIT_HEAD_ID or
isl/configure{,.ac}.
