Compilation steps on AIX 5.3 using gcc+stlport

[GoogleCodeExporter]

Just leaving a reminder in order to make it easier for the few unlucky others 
who need to make this work on this unpleasant platform combination.

First one must patch template_dictionary.cc and tests/statemachine_test.c using 
the attached patch file (WARNING, not fully tested yet)

then one must use the magic incantation

export STLPORT_HOME=/whatever

CC="g++" \
CXXFLAGS="-I$STLPORT_HOME/include/stlport -D_REENTRANT -D_LINUX_SOURCE_COMPAT 
-D_THREAD_SAFE -D_LARGE_FILE_API" \
LDFLAGS="-L$STLPORT_HOME/lib" \
LIBS="-lstlport -lpthread -lstdc++" \
../ctemplate-2.0/configure

reasons for this:
- patch in template_dictionary.cc: this is because int64 gets defined as long 
long int somewhere so I simply use long both in the headers and the 
implementation
- patch in statemachine_test.c: this is because I compile everything with g++ 
so the #ifdef(__cplusplus) in statemachine.h is not a good discrimination of 
what is being compiled. The solution is to use the statemachine namespace in 
the .c file
- -D_REENTRANT and -D_THREAD_SAFE are stlport configuration options
- -D_LINUX_SOURCE_COMPAT makes AIX headers more linux-y
- LIBS="-lstlport -lpthread -lstdc++" makes it possible to compile configure 
tests and get on, without those pthread support cannot be detected and 
compilation fails on arena.cc

I realise this is not a fully working solution (and yes: AIX+gcc is totally 
unsupported) but for the unlucky it's a start ;)
