Does it work if you replace -b with -Z in archive_cmds,
archive_expsym_cmds inside the libtool script?

I agree.

Works here on 11.00 with
cpp.ansi: HP92453-01 B.11.X.35175-35176.GP HP C Preprocessor (ANSI)
ccom: HP92453-01 B.11.X.35098-35101.GP HP C Compiler

OTOH this compiler on 10.20 warns about -b, too:
cpp: HP92453-01 A.10.32.30 (WM) HP C Preprocessor
ccom: HP92453-01 A.10.32.30 HP C Compiler

Hmm.  I don't recall.

Seems like we need a compile test.

Thanks for the bug report!

Cheers,
