The reason is to make it so specific. :-) The rule 'mstypelib' converts
Microsoft IDL into Microsoft type library. Other IDL compilers will use
own rules that will make similar conversions. For instance 'xptypelibe'
will convert an XPIDL file (.idl) into XPConnect type library (.xpt).

This is also the way to resolve the ambiguity when that same extension
.idl means can be used by different IDL dialects.

The IDL file is specified by the response file. It should not be present
in the command line. I remember Vladimir told that there is a problem
with tracking dependencies on response files - BB does not regenerate
response file correctly if the way .jam has been changed. Try to delete
all 'bin' directories and build again.

"myidl.h" is a generated header, right? Vladimir should look at this issue.

Give me some time to play with it.

I check this one too.
