Summary of my perl5 (revision 5.0 version 6 subversion 1) configuration:
Platform:
osname=solaris, osvers=2.6, archname=sun4-solaris
uname='sunos penq 5.6 generic_105181-21 sun4u sparc sunw,ultra-60 '

useperlio=undef d_sfio=undef uselargefiles=define usesocks=undef
use64bitint=undef use64bitall=undef uselongdouble=undef
Compiler:
cc='gcc', ccflags =' -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64',
optimize='-O',
cppflags=''
ccversion='', gccversion='2.8.1', gccosandvers='solaris2.6'
intsize=4, longsize=4, ptrsize=4, doublesize=8, byteorder=4321
d_longlong=define, longlongsize=8, d_longdbl=define, longdblsize=16
ivtype='long', ivsize=4, nvtype='double', nvsize=8, Off_t='off_t', lseeksize=8
alignbytes=8, usemymalloc=y, prototype=define
Linker and Libraries:
ld='gcc', ldflags =' -L/usr/local/lib '
libpth=/usr/local/lib /usr/lib /usr/ccs/lib
libs=-lsocket -lnsl -ldl -lm -lc
perllibs=-lsocket -lnsl -ldl -lm -lc
libc=/lib/libc.so, so=so, useshrplib=false, libperl=libperl.a
Dynamic Linking:

cccdlflags='-fPIC', lddlflags='-G -L/usr/local/lib'

The compile and link lines look like this:
gcc -c -fPIC -DPRO_MACHINE=19 -DPRO_OS=3 -DSOLARIS -I. -Iincludes
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64
-I/usr/perl/lib/5.6.1/sun4-solaris/CORE properl.c
ld -G -Bsymbolic -o properl.dll properl.o ./protk_dll.a
/usr/perl/lib/5.6.1/sun4-solaris/auto/DynaLoader/DynaLoader.a
-L/usr/perl/lib/5.6.1/sun4-solaris/CORE -lperl
-L/opt/gcc-2.95.3/lib/gcc-lib/sparc-sun-solaris2.6/2.95.3 -lgcc
-lsocket -lnsl -lw -lm -ldl -lc
The link step (using ld) is modified by setting '-G -Bsymbolic', then linking
in the cad api library (protk_dll.a), 'libgcc' (probably should just use gcc
for linking), and 'libw'.
My perl says this (which you probably already know):
% perl -MExtUtils::Embed -e ccopts
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/perl/lib/5.6.1/sun4-solaris/CORE
% perl -MExtUtils::Embed -e ldopts
-L/usr/local/lib /usr/perl/lib/5.6.1/sun4-solaris/auto/DynaLoader/DynaLoader.a
-L/usr/perl/lib/5.6.1/sun4-solaris/CORE -lperl -lsocket -lnsl -ldl -lm -lc

Simple perl scripts run great, so I'm very happy with that. The
XS module portion is a piece of cake in comparison.
Thanks for the help,
