From deraadt@ upstream:
Remove all getenv() calls, especially those wrapped by issetugid().
getenv()'s wrapped by issetugid() are safe, but issetugid() is ...
difficult to impliment on many operating systems. By accident, a grand
experiment was run over the last year, where issetugid() returned 1 (the
safe value) on a few operating systems. Noone noticed & complained that
certain environment variables were not working.......
Move define adjustments to CPPFLAGS.
Adjust user CFLAGS directly, do not override during configuration.
USER_CFLAGS is not necessary to build libcompat_noopt correctly.
The current NetBSD release, 6.1.5, fails to reseed arc4random fork. Work
around it by providing arc4random/getentropy shims. Revisit when NetBSD
7 is available.
tested on: HP-UX 11.31 ia64,
gcc 4.7.1(HP AllianceOne version)
gcc 4.2.3(http://hpux.connect.org.uk)
HP C/aC++
HP-UX defaults to use LP32 and it treats long as 32 bit (= 4 bytes).
This build forces LP64 for treating long as 64 bit.
This adds initial support for assembly crypto acceleration on x86_64 for
ELF (Linux, *BSD, Solaris) and Mach-O (OS-X) systems.
The build method is a little different than OpenSSL and OpenBSD. All
the .s files are generated ahead of time when the tarball is generated,
so there are no complicated makefile rules at configure/build time. This
also means the builds are faster and perl is not required on the build
system.
Thanks to Wouter Clarie for providing the initial cleanup and patch
that this is based on.
This makes building and testing easier because the library Makefile.am
files are use directly rather than as templates. Thanks to Wouter Clarie
for the idea.
