Move 4.01 onto the main trunk.

Emit soothing msg to counter the (harmless) autoconf warning that is output while processing AC_C_BIGENDIAN

Added f-checks for symlink() and readlink()

Added tests required by Hugs

Default WithGhcHc is now just "ghc".  Too many people complained.

Add support for FreeBSD 3.0 (ELFish).
Rename i386-unknown-freebsd to i386-unknown-freebsd2, and add
i386-unknown-freebsd3.

NOTE: this won't bootstrap an ELF GHC using an a.out GHC, some laying
on of hands is required for that.

added use of FPTOOLS_CODE_BEFORE_DATA, FPTOOLS_END_DATA_SECTION, FPTOOLS_END_TEXT_SECTION

Tidied up a bit + added --with-ghc-hc option

Doc string for --enable-hc-boot was lacking; added --with-gcc cmd line option

check for netinet/tcp.h (apparently needed for some socket options on
FreeBSD).

Oops, last commit left out this file

Check if (struct stat) has st_blksize

apparently GMP is installed as libgmp2.a on Debian systems.

Added long long feature test; macro namespace cleanup

Remove lx feature test (unused)

Added test for libiberty.a (needed by libbfd.a)

Added test for bfd.h and libbfd

Added --enable-hc-boot flag for setting up a .hc build tree

- check for an installed libgmp 2.0.x

- check endianness of host (this test for some reason
  generates a warning from autoconf, but it seems harmless)

- move SIZEOF checks together (previous commit added SIZEOF checks to
   a different part of the file).

 - check alignment of longs:  unsigned ints are no good, because we need to
   check whether f.e. a float can be put on the stack, which is
   StgWord aligned, and currently an StgWord is basically a long.

Added alignment tests

Add some size tests.

back out last commit until we've decided how to do these properly.

Added more feature tests

don't look for green-card binary, use the one in the
build tree instead.

Do UNC->DOS translation of TOP_PWD

alpha-dec-osf1 and alpha-dec-osf3 are now separate configurations.

AC_SUBST(exeext)

bogus '/' crept in.

add yet more hacks for tmp_mnt, this time to deal with amd-style mount
points.

minor mod to the happy configuration.

If the installed version of Happy is < 1.3, use the one from the tree.

Moved feature tests from configure.in to aclocal.m4 and macroified them

Cleaned up; moved custom-checks to aclocal.m4; fixed lead_uscore problem on alphas

Added test for greencard

removed HostPlatformFull; added HostOS_Full(==host_os)

2.04 updates

AIX

Made perl library test non-fatal

Look for readline.h
