Hello,
in general, "The Autoconf Way" is to check for feattures, not for
platform name.
For example:
*-cygwin*)
EXE_EXT=".exe"
A variable "EXEEXT" is provided automatically by Autoconf.
And the detection works also for mingw and all other platforms.
case "$host" in
*-sun-solaris*)
CFLAGS="$CFLAGS -DSunOS=1"

This hack might be necessary, though. I'm not sure what you want
to achieve.
But if you are using Automake, then
AC_SUBST([AM_CPPFLAGS], [-DSunOS=1])
might be more appropriate here.
No automake for me yet ;)
[...] configure acts absolutely crazy

There is nothing crazy here. Perhaps there are some headers have
to be included
before sys/ioctl.h? Look into config.log, to see details.
After commenting out AC_CHECK_LIB, all header checks were ok. Really
crazy things are:
checking whether we are using the GNU C compiler... no (i certainly
use it)
checking for ANSI C header files... no
checking for sys/types.h... no
checking for sys/stat.h... no
checking for stdlib.h... no
checking for string.h... no
checking for memory.h... no
checking for strings.h... no
checking for inttypes.h... no
checking for stdint.h... no
checking for unistd.h... no
Darwin gcc has none of C standard libraries ? It does have.
checking for short... no
checking size of short... 0
checking for int... no
checking size of int... 0
checking for long... no
checking size of long... 0
checking for long long... no
checking size of long long... 0
And no integer types ?
All this changes after commenting out.
*-*-openbsd* | *-*-freebsd*)
CFLAGS="$CFLAGS -pthread"
ac_ext=c
ac_cpp='$CPP $CPPFLAGS'
...
So, autoconf just drops the end of the case statement.
No, it doesn't, the esac is somewhere below. It just happens that the
expansion of AC_CHECK_LIB is that long.
Ok, but there must be some reason for failing of all standard tests.
But it seems AC_SEARCH_LIBS might be more appropriate here:
AC_SEARCH_LIBS([pthread_exit], [c_r kse], [pthread=yes])
It also modifies LIBS; see the manual for details.
Thanks. I try this.
HTH,
Stepan
