Summary

0000633: FIXED: wrong 32/64 bit integer typedefs for MSVC compiler

Description

The integer typedefs for the Microsoft Visual C++ compiler located in lines 159 and 174 of "ap.h" are using deprecated type names. The typedefs use the "_int32" and "_int64" types (prefixed with a single underscore), which are only defined when compiling with Microsoft C++ Language extensions enabled (which is the default). Disabling these extensions explicitly by supplying the "/Za" compiler option leads to the following errors:

ap.h(159): error C2146: syntax error : missing ';' before identifier 'ae_int32_t'
ap.h(159): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
ap.h(174): error C2146: syntax error : missing ';' before identifier 'ae_int64_t'
ap.h(174): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

This problem can be resolved easily by replacing the (single-underscore) "_int32"/"_int64" type names by the (double-underscore) "__int32"/"__int64" types, resp., see:
