IIRC the C standard requires
{{{sizeof(short) <= sizeof(int) <= sizeof(long)}}}
but also
{{{sizeof(short) < sizeof(long)}}}
so Cray would violate the latter.

You mean I should upload a reviewer patch? ;-)

not implemented. I've only done this on the compilers gcc, g++ and
gfortran.
The linker isn't often used directly, and {{{libtool}}} calls {{{gcc}}}
for linking:
{{{
#!sh
ld -shared -o p_Procs_FieldIndep.so p_Procs_Lib_FieldIndep.dl_o
ld -shared -o p_Procs_FieldZp.so p_Procs_Lib_FieldZp.dl_o
ld -shared -o p_Procs_FieldQ.so p_Procs_Lib_FieldQ.dl_o
ld -shared -o p_Procs_FieldGeneral.so p_Procs_Lib_FieldGeneral.dl_o
ld -shared -o dbmsr.so ndbm.dl_o sing_dbm.dl_o -lc_nonshared
}}}
(That's all.)
