Building Issues on BGL

[Satish Balay]

You have to remove the defines or rename them to something else in
petscconf.h. Just commenting or undefining doesn't work. [this is
because our build system does a grep on this file - so its doesn't
exactly follow preprocessing directives]

Regarding the original issue - I'm not sure why it doesn't work. We
have V1R3M0_460_2008-081112P on our BGP - and I don't remember seeing
this issue.

Also - note; logfiles configure.log etc. should be sent to petsc-maint
- and not the mailing list [we don't want to flood huge log files to
all folks on this list]
