g++ 2.8 works OK and newer egcs work well also. Nobody has tried it
on other compilers :< You will need a properly working STL as well.

Guidelines
~~~~~~~~~~
to make the code that already exists conform more to SUS or POSIX, but
I don't really care if your not-SUS OS doesn't work. It is simply too
much work to maintain patches for dysfunctional OSs. I highly suggest you
-contact your vendor and express intrest in a conforming C library.

+That said, there are lots of finicky problems that must be dealt with even
between the supported OS's. Primarily the path I choose to take is to put
a shim header file in build/include that transparently adds the required
functionality. Patches to make autoconf detect these cases and generate the
required shims are OK.
Current shims:
- * C9x integer types 'inttypes.h'
- * sys/statvfs.h to convert from BSD/Linux statfs to SUS statvfs
+ * sys/statvfs.h to convert from BSD/old-glibc statfs to SUS statvfs
* rfc2553 hostname resolution (methods/rfc*), shims to normal gethostbyname.
+ The more adventurous could steal the KAME IPv6 enabled resolvers for those
+ OS's with IPv6 support but no rfc2553 (why?)
+ * define _XOPEN_EXTENDED_SOURCE to bring in h_errno on HP-UX
+ * socklen_t shim in netdb.h if the OS does not have socklen_t
-The only completely non-shimed OS is Linux with glibc2.1, glibc2.0 requires
-all three shims.

-
- #define _XOPEN_SOURCE_EXTENDED
