The metaconfig probe for <db.h> previously relied on the d_const symbol set
by the "const" probe, so generating Configure here has been done against
metaconfig commit 1204d4627a06b11f16620188f3fa83159ed35fd9 which changes
that.
Thanks to khw++ for pointing out this oversight in my attempt last year to
make the codebase rely on C89.

This reverts commit 8e920bd341e241f50a74dbf8aa343319f204e200.
Also skip the tests in t/op/blocks.t
RT #132863
8e920bd341 sets the PERL_EXIT_DESTRUCT_END flag on non-UNIXy platforms,
like is already done on UNIXy platforms. This makes things like
BEGIN { exit(1) } call END blocks on those platforms (like they already
do on UNIX).
But it caused problems with win32 pseudo-forks, so revert for 5.28
and re-address the issues sometime later.

Most of the change here comes from a single unit being moved in the
generated Configure, but there are some substantive changes:
- config_h.SH was missing HAS_DUPLOCALE and d_duplocale
- d_duplocale was also missing from the platform-specific config-var files
This still doesn't quite ensure that rebuilding Configure makes no changes,
because there are differences to nl_langinfo() handling that need a change
in our metaconfig units. That will come next.

This is another file descriptor creating function that's needed as an
O_CLOEXEC-handling variant of an existing function.
|
|
|
|
|
| |
These will shortly be used to implement I/O operations that create file
descriptors with the FD_CLOEXEC flag set atomically.

The new tests in commit 503bc07b4b9e34ed04a725b2bc8faec1ae0f3be2
showed up platform differences in whether END blocks get run.
Set PERL_EXIT_DESTRUCT_END in all embeddings to make this consistent.

Some platform-specific embeddings of perl were misusing the
return values from perl_parse() and perl_run(), in some cases
causing failure due to exit(0) combined with the recent changes
in commit 0301e899536a22752f40481d8a1d141b7a7dda82. Commit
d4a50999a5525c2681d59cae5fcd94f94ff897fd partially fixed a Windows
embedding. More fully fix that, along with NetWare and OS/2. Even in
embeddings with correct logic, stop using a variable named "exitstatus"
to hold the result of perl_parse() or perl_run(), to avoid misleading
people who copy the code.

C89 does not in fact define snprintf() or vsnprintf(), and we must therefore
probe for the existence of those functions before trying to use them.
khw++ for pointing out my earlier error.
This reverts part or all of each of the following commits:

This requires a corresponding change in the metaconfig units.

It's only needed on systems without C89 <string.h>, which we rely on anyway.

All the information it contains can be gleaned more readily from C89
<limits.h> and <float.h>.

I would like to be able to assume that we have long doubles, and therefore
that LDBL_DIG and friends are all defined too. But it seems that we may
still support some platforms which are otherwise C89, but don't have even
trivial long-double support; in particular, HP/UX 10 apparently uses a
struct of four uint32_t values as long double, but doesn't support other
bits, and confuses the Configure probe that looks for quadmath.

This requires newer metaconfig units that also rely on C89 <float.h>.

This needs a metaconfig change that defangs the standard unit for finding
strchr(), because that unit sees the uses of "index" and "rindex" (in files
like keywords.c and opcode.h) as indicators that it must be used instead.

The Configure changes here were generated using a version of metaconfig
that copies U/modified/i_stdlib.U from dist/U/vaproto.U, and changes it to
unconditionally define the i_stdlib Configure variable. That variable is
used by a large number of other Configure units, so it's not actually
practical to try and remove the relevant unit entirely.
