HP-UX

waiting for you replies

Can you type model, so we know what you are on (32 or 64 bit box)?

I am no C developper, and rarely compile using ansic, but I remember HP compiler does not like at all variables definitions that are not initialized... other compilers (IBM...) dont care ( I suspect they do the job for you.. (But not always and you can end with odd results...)

Now you could try and download a GCC bundle and give a try ( I do for GNU stuff).

What puzzles me also is the ownership of your transition link /usr/bin/cc,there are others:
/bin/cc -> /opt/ansic/bin/cc
/lib/ccom -> /opt/ansic/lbin/ccom
/bin/c89 -> /opt/ansic/bin/c89

/usr/bin/cb -> /opt/ansic/bin/cb
/usr/bin/cflow -> /opt/ansic/bin/cflow
/usr/bin/cxref -> /opt/ansic/bin/cxref
/usr/bin/endif -> /opt/ansic/bin/endif
/usr/bin/lint -> /opt/ansic/bin/lint
/usr/bin/protogen -> /opt/ansic/bin/protogen
/usr/lib/dag -> /opt/ansic/lbin/dag
/usr/lib/flip -> /opt/ansic/lbin/flip
/usr/lib/lint2 -> /opt/ansic/lbin/lint2
/usr/lib/lpfx -> /opt/ansic/lbin/lpfx
/usr/lib/nmf -> /opt/ansic/lbin/nmf

go and check what is in /opt/ansic, it should all be bin:bin r-xr-xr-x

If your compiler accepts -Ae option, you have the advanced compiler.
gcc is also available for HP UX 11.11 - I don't think it will help

Does your editor do bracket matching? Try to find the curly bracket that matches the one it is complaining about - then look to see if the correct curly bracket is available.
