Hello lonetiger,
I don't think any relevant logic changed in 7.10; however, this
commit may be relevant:
commit 8fb03bfd768ea0d5c666bbe07a50cb05214bbe92
Author: Ian Lynagh <ig...@earth.li> Sun Mar 18 11:42:31 2012
Committer: Ian Lynagh <ig...@earth.li> Sun Mar 18 11:42:31 2012
Original File: compiler/typecheck/TcForeign.lhs
If we say we're treating StdCall as CCall, then actually do so
But this warning should have applied even on older versions of GHC.
Are you running x86_64 Windows? stdcall is specific to x86_32.
