Ok, this is comming from the configure test "checking for $CC option to
accept ANSI C". This option shouldn't be used for the libstdc++ build
but obviously it is...
In order to build GCC 3.4 and later, you need an ANSI compiler. You
also need to include the full HP-UX namespace The "struct stat" error
probably is a result of not providing the appropriate namespace defines
in you CC define. -Aa provides strict ANSI. For example, these are
the defines that I use for GCC builds prior to 4.0 under HP-UX 11.11:
-D_HPUX_SOURCE -D_XOPEN_UNIX -D_XOPEN_SOURCE_EXTENDED
-D_INCLUDE__STDC_A1_SOURCE -D_INCLUDE_XOPEN_SOURCE_500
-D_HPUX_SOURCE is the important define. The others are needed for C++
library support (wide characters, etc).
Instead of trying to build C++ starting with an HP compiler, it's easier
to just build C and then use this compiler to rebuild GCC with the additional
languages that you want. It's always been tricky to bootstrap GCC using
an HP compiler and its not tested much. You should use binutils (current
CVS version is needed with GCC 4.1 and later for EH exception support).
