autoconf macro archive, to fix pthread linking problem on Solaris
|
||||
10, reported by Charles Gagnon.
|
||||
|
||||
2006-05-28 Kevin Ryde <user42@zip.com.au>
|
||||
|
||||
* configure.in (isnan): Remove "#ifdef __MINGW32__, #define isnan
|
||||
_isnan". Mingw provides isnan as a macro (in math.h), the test
|
||||
already detects it just fine with no special case.
|
||||
|
||||
2006-05-26 Kevin Ryde <user42@zip.com.au>
|
||||
|
||||
* configure.in (AC_CHECK_FUNCS): Add ioctl.
|
||||
(pthread_attr_getstack): Restrict test to pthreads case, to avoid
|
||||
AC_TRY_RUN when cross-compiling --without-threads.
|
||||
|
||||
2006-05-20 Kevin Ryde <user42@zip.com.au>
|
||||
|
||||
* configure.in (S_ISLNK): Remove test, leave it to #ifdef in the .c
|
||||
files.
|
||||
|
||||
2006-05-16 Kevin Ryde <user42@zip.com.au>
|
||||
|
||||
* configure.in (struct stat st_blocks): Change AC_STRUCT_ST_BLOCKS to
|
||||
a plain AC_CHECK_MEMBERS, we don't want AC_LIBOBJ(fileblocks) which
|
||||
the former gives. Remove the commented-out code that was to have
|
||||
munged fileblocks out of LIBOBJS. This fixes mingw, where the lack of
|
||||
st_blocks and absense of the fileblocks.c replacement caused build
|
||||
failure. Reported by "The Senator".
|
||||
(struct stat st_rdev, st_blksize): Combine into a single
|
||||
AC_CHECK_MEMBERS.
|
||||
|
||||
2006-04-18 Rob Browning <rlb@defaultvalue.org>
|
||||
|
||||
* configure.in: Add AC_CONFIG_AUX_DIR([.]) as suggested in the
|
||||
autotools documentation.
|
||||
|
||||
2006-04-16 Kevin Ryde <user42@zip.com.au>
|
||||
|
||||
* configure.in (stat64, off_t): New tests.

Terminate the current process without unwinding the Scheme stack. The

@code{primitive-exit} uses the C @code{exit} function and hence runs

Scheme-level nor C-level cleanups.

The typical use for @code{primitive-_exit} is from a child process
|

created with @code{primitive-fork}. For example in a Gdk program the

child process inherits the X server connection and a C-level
|

@code{atexit} cleanup which will close that connection. But closing

in the child would upset the protocol in the parent, so

@code{primitive-_exit} should be used to exit without that.
