## If the Fortran compiler is gfortran >= 7, R used to add
## -fno-optimize-sibling-calls to avoid recent gfortran optimizations
## that break with LAPACK/BLAS-style passing of length-1 strings
## (without hidden arguments giving their lengths).
##
## One could also use -ftail-call-workaround=2, which would be less
## restrictive, and has been added after the breakages were discovered.
## However, it is documented that this option may be removed in the future.
## https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90329
##
## -fno-optimize-sibling-calls is no longer forced once all packages are
## passing char lengths.
