perfectly safe [compiler driver adds it] and in some situation even
perfectly appropriate [mixing -pthread and -lc on FreeBSD can have
lethal effect on apps/openssl]. I'd say we should get rid of more,
but I remove those I can test myself...
Makefile.shared was a bit overcomplicated.
Make the shell variables LDFLAGS and SHAREDFLAGS in Makefile.shared
get the values of $(CFLAGS) or $(LDFLAGS) as appropriate depending on
the value the shell variables LDCMD and SHAREDCMD get. That leaves
much less chance of confusion, since those pairs of shell variables
always are defined together.
"remaining relocations" in assembler modules. The latter seems to
be new behaviour, elder as/ld managed to resolve this relocations
as internal. It's possible to address this problem differently,
but I settle for -Bsymbolic...

COFF and a.out targets [similar to ELF targets]. You might notice some
rudementary support for shared mingw builds under cygwin. It works (it
produces cryptoeay32.dll and ssleay32.dll with everything exported by
name), but it's primarily for testing/debugging purposes, at least for
now...
For reference. Note that both cc and gcc support -Wl flag, but we can't
use -Wl,-[not]all with both drivers, because cc rearranges options
passed through -Wl. We can't use -Wl,-all,libcrypto.a,-notall with cc
either, because it refuses to start with "no input" error.
libraries. What's worse, the directories given in LD_LIBRARY_PATH are
checked first! Therefore, we need a hack to prepend all the
directories we give with -L to the current value of LD_LIBRARY_PATH,
thereby temporarly forming a hacked value.
Only copy LIBEXTRAS if they are given.
Svr5 doesn't use -z allextract...
applications, at least on the platforms where it's known how
to do it.
Note: this has only been tested on GNU-based platforms (Linux), and
needs to be tested on all others. Additionally, it's not yet
supported on the following platforms, for lack of information:
Darwin (MacOS X)
Cygwin
OSF1/Alpha
SVR3
ReliantUNIX
Please help out with testing and the platforms we don't yet know well
enough.
