Hi!

I have noticed we don't export these 6 symbols and thus the testcase
below fails to link.

Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux, ok for
trunk and 10.2?

2020-05-28  Jakub Jelinek  <jakub@redhat.com>

	PR libfortran/95390
	* gfortran.dg/findloc_8.f90: New test.

	* Makefile.am (i_findloc0_c): Add findloc0_i10.c.
	(i_findloc1_c): Add findloc1_i10.c.
	* gfortran.map (GFORTRAN_10.2): New symbol version, export
	_gfortran_{,m,s}findloc{0,1}_c10 symbols.
	* Makefile.in: Regenerated.
	* generated/findloc0_c10.c: Generated.
	* generated/findloc1_c10.c: Generated.
