/*  Many sections come in three flavours.  There is the 'real' section,
    like ".data".  Then there are the per-procedure or per-variable
    sections, generated by -ffunction-sections and -fdata-sections in GCC,
    and useful for --gc-sections, which for a variable "foo" might be
    ".data.foo".  Then there are the linkonce sections, for which the linker
    eliminates duplicates, which are named like ".gnu.linkonce.d.foo".
    The exact correspondences are:

    Section	Linkonce section
    .text	.gnu.linkonce.t.foo
    .rdata	.gnu.linkonce.r.foo
    .data	.gnu.linkonce.d.foo
    .bss	.gnu.linkonce.b.foo
