    _______________________________________________________

Details:

a recent dev version fails to build with QR related errors, whereas the build
was successful up to recently.

cfg output:

  SPQR CPPFLAGS:
  SPQR LDFLAGS:
  SPQR libraries:                -lspqr
  SuiteSparse config libraries:  -lsuitesparseconfig -lrt


more cfg output:

This is the first error, involving a mismatch in argument numbers:
