A minor point maybe, but, as you say, there seem to be several  
different schemes in use... a source of confusion for me whilst  
trying to figure out how to do this.

I was almost going to rename the shared one _s (as per libgcc) :-)

j/k aside is there a convention ?

I don't mind (I prefer '-' to '_' personally;    '_static'  and  
'_kext' were used in the 4.0.1 vendor release for darwin8).

Yes, it does make three libs - only a temporary measure to avoid  
treading on anyone else whilst testing (see below).

The "-static-libgfortran" option causes it to pick up the _static  
version  (patch to gfortranspec.c).

AFAIK there is no point in doing a "-static" link on darwin [crt0 is  
not present] (unless you're making a kernel extension).
However, the proposed change makes no difference to what will happen  
if you do.

You are right;  of course, it should be darwin-specific (and only  
build the required libs per system)
-  but I am not familiar enough with the build process to know how  
best to achieve that... suggestions welcome.
