Nope - it's not harmless. InlinetestLib.lib needs to be found. Where is it ?
(I think it might have been created when you built the dll ... but I'm not
sure about that.)
If you don't have it, can you tell me how the dll was built - ie which
command(s) did you run.

The compiler doesn't like the way InlineTestLib.h is written. Did you get
the same problems when you built the dll ?

The location is incorrectly specified. Perhaps that's why the file can't be
found. Should be:
LIBS => '-LE:\Sankaran\Work\TP-TAImpacts-LM051049\PerlInline\MyTest1

> INC => '-I\E:\Sankaran\Work\TP-TAImpacts-LM051049\PerlInline\MyTest1',

Change to:
INC => '-IE:\Sankaran\Work\TP-TAImpacts-LM051049\PerlInline\MyTest1',
