Problems while linking

Hello,
The compilation for v4.7 keeps breaking while linking everything together. The issue seems to originate from mediation_interp_domain, but the object (mediation_interp_domain.o) has interp_domain_em_part1_, interp_domain_em_part2_, interp_domain_em_part3_, interp_domain_em_small_part1_ & interp_domain_em_small_part2_, and the library has picked up the object. The only difference versus v4.6 is the addition of 'interp_domain_em_part3' but cannot figure out why this would causes the linking to fail. I noticed that interp_domain_em_part1, interp_domain_em_part2 and interp_domain_em_part3 seem to do the same, but that's more a matter of coding style, not sure if this would cause the compilation error.
Thanks.

Not sure if I understand why this is an issue with v4.7, but not with previous version. Anyway, the fix worked. Thanks.
Note: Without the fix, the source files were compiled and libraries were built, but linking everything together failed.
 
v4.6.1 split these functions out into separate files with this PR : Break out module_dm external subroutines into separate files by islas · Pull Request #2069 · wrf-model/WRF

So the changes are fairly recent and would have been missed in any version <= v4.6.0

Interestingly, the fix should already be in v4.7.0 and I can't find any other stanzas that are missing the DMPARALLEL = # 1 line. I'd be interesting in seeing your configure.wrf and which stanza you used, just to make sure no one else runs into this issue as well.
