Follow-up Comment #2, bug #62715 (project octave):
@Markus: It seems possible that the change is related.
Is there something weird about w32-on-debian build? Is it a cross compile,
for example, where some configure tests might get skipped and therefore the
value for ax_cv_blas_integer_size is never set?
In configure.ac I see
OCTAVE_BLAS_WITH_F77_FUNC([], [],
[ax_blas_ok=yes
AC_MSG_CHECKING([BLAS can be called from Fortran])
AC_MSG_RESULT([yes assumed for cross compilation])])
And in octave_blas_f77_func.m4 I see this in the documentation
# AX_BLAS_F77_FUNC([ACTION-IF-PASS[, ACTION-IF-FAIL[,
ACTION-IF-CROSS-COMPILING]])
Also, at the top of the code for the Autoconf macro I see
if test "$cross_compiling" = yes ; then
ifelse($3, ,$1,$3)
So, this is very likely related to the cross compiling. I don't know what the
desired result is here. Should we just assume 4-byte BLAS library when cross
compiling?
