# See extra explanation in info.md
#
# For future reference: if you see the following errors:
#   Declaration error: adjustable dimension on non-argument
# or:
#   nonconstant array size
# you are trying to compile code that isn't written to the fortran 77 standard.
# The line number in the error points to the last line of the problematic
# subroutine. Try deleting it.

  # IMPORTANT: Other locations important in scipy build process:
  # There are two files built in the "capture" pass that need patching:
  #    _blas_subroutines.h, and _cython
  # Scipy has a bunch of custom logic implemented in
  # pyodide-build/pyodide_build/_f2c_fixes.py.
