Fix compile-time assertion to test the right thing

The assertion needs to test that the *public* definition of the 32-bit character
is a 32-bit integer type, not the *private* definition.

121 /* When compiling a DLL for Windows, the exported symbols have to be declared
122 using some MS magic. I found some useful information on this web page:
123 http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
124 information there, using __declspec(dllexport) without "extern" we have a
125 definition; with "extern" we have a declaration. The settings here override the
126 setting in pcre.h (which is included below); it defines only PCRE_EXP_DECL,
127 which is all that is needed for applications (they just import the symbols). We
128 use:
129
130 PCRE_EXP_DECL for declarations
131 PCRE_EXP_DEFN for definitions of exported functions
132 PCRE_EXP_DATA_DEFN for definitions of exported variables
133
134 The reason for the two DEFN macros is that in non-Windows environments, one
135 does not want to have "extern" before variable definitions because it leads to
136 compiler warnings. So we distinguish between functions and variables. In
137 Windows, the two should always be the same.
138
139 The reason for wrapping this in #ifndef PCRE_EXP_DECL is so that pcretest,
140 which is an application, but needs to import this file in order to "peek" at
141 internals, can #include pcre.h first to get an application's-eye view.
142
143 In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
144 special-purpose environments) might want to stick other stuff in front of
145 exported symbols. That's why, in the non-Windows case, we set PCRE_EXP_DEFN and
146 PCRE_EXP_DATA_DEFN only if they are not already set. */

1230 the characters so that they always use the ASCII/UTF-8 code when UTF-8 support

1232 literals. Both character and string versions of each character are needed, and
1233 there are some longer strings as well.

1235 This means that, on EBCDIC platforms, the PCRE library can handle either
1236 EBCDIC, or UTF-8, but not both. To support both in the same compiled library
1237 would need different lookups depending on whether PCRE_UTF8 was set or not.
1238 This would make it impossible to use characters in switch/case statements,
1239 which would reduce performance. For a theoretical use (which nobody has asked
1240 for) in a minority area (EBCDIC platforms), this is not sensible. Any
