#3042: rts defines "real_main" which can clash with user C code

Priority: normal | Component: Runtime System
Version: 6.10.1 | Severity: normal

Os: Unknown/Multiple | Architecture: Unknown/Multiple
-----------------------------+----------------------------------------------
I was just about to file a bug about `ghc -no-hs-main` not working but it
turns out it is just because I had a `real_main` C function in my `.c`
file. This ends up clashing with the C function of the same name from the
rts package. This means that when linking we pull in the wrong one and the
rts one needs `__stginit_ZCMain` and `ZCMain_main_closure` which is what
the linker error message reports (which is rather confusing).
Suggestion: rename the rts `real_main` to something less likely to clash
with user code.
