Huh, BG/P and /Q are outliers.  All of the compiler scripts went through (I
believe) gcc to do the final link, which meant they properly brought in the
external libraries required by C++/Fortran.  They also promised C ABI
compatibility between the XL compilers and GCC, which I guess is standard
these days.

zsh 10219  (git)-[master]-% gfortran -Wl,-v foo.f90
