HP-UX 11.00 linkage questions

[Richard Davies <richy dot boy at clara dot co dot uk>]

Hi,

To start with..

I've built gcc 3.0 for vanilla HP-UX 11.00 (btw ltconfig breaks in the 
section starting line 779 when finding maximum length of command line 
arguments when configuring libstdc++-v3). 
Everything works fine and I am more than pleased at only having to add 
one line direct to the config cache files to fix this, compared to some 
previous gcc versions.

My question(s) are related to linkage though and this may not be 
possible at all.. but anyway, here we go.

I want to use gcc to compile all my source files, but use native aCC (
ld) to link them as there are several 3rd party ISV libraries that I 
want to link to but alas have been built with aCC.

I notice a couple of interesting switches, -fno-gnu-linker and -funwind-
table. I don't pretend to know a lot about collect2 and the way gcc 
creates global code for object construction, but after using those 
switches, and linking (I assume gcc collect2 uses the native ld anyway 
hence the general compatability of symbols) I am still left with 

_Unwind_SjLj_Register
_Unwind_SjLj_Resume
_Unwind_SjLj_Unregister

Linking against libgcc will naturally fix this, but also naturally it 
breaks the executable. This is with a dead simple dummy class and an 
equally trivial main in a different translation unit. I was rather 
hoping the -funwind-tables and -fno-gnu-linker would do away with this 
particular hardship.

Advise would be appreciated, particulary the 'can this be done' 
question. If it can't be done easily, what do I need to know to build 
that collection of (presumably sjlj exception style) handlers ?
