[lmi] questionable code checking for e_currbasis in ihs_acctval.cpp

[Vadim Zeitlin]

 Hello again,

 There are 4 occurrences of the following expression in ihs_acctval.cpp:

        !e_currbasis == ExpAndGABasis

which attracted my attention because MSVC complained about 

        '==' : unsafe mix of type 'bool' and type 'int' in operation

for each of them.

 The error message is not very precise but I think that there could be a
real problem here because the above compares ExpAndGABasis with the result
of negating e_currbasis (which happens to be 0), i.e. 1 (which happens to
be e_guarbasis. I'm not at all sure that this was the intention and if it
was I still think that the code should be changed to read

        e_guarbasis == ExpAndGABasis

But maybe the real intention was

        e_currbasis != ExpAndGABasis

?

 Thanks,
VZ
