Fwd: Re: pnetcdf 0.8.8 release

[William Gropp]

One thing to consider is the use of a "cross file" such as MPICH2 
uses.  For each test that must be run, the environment variable CROSS_XXX 
provides the value for the cross-compilation case (e.g., 
CROSS_SIZEOF_INT).  A --enable-cross=crossfile can cause configure to load 
a file containing the definitions (provided separately by the user, or, 
also a in MPICH2, with a *single* program that writes out all of the 
necessary values).
