to avoid seg-fault. Also the NULL filename will cause ParseVErrorInternal
to skip trying to report file and line number info.
If CondToken is called outside the context of a .if etc, variables in
the expression being parsed will already be expanded, so allow for
an unqouted number to jump us back into the compare logic.
This allows ${${SomeNumber:U42} > 0:?True:False} to work anywhere.
Job_Finish should process postCommands if it has commands or children.
is enabled but debugging output is not directed to stdout, then make
stdout line buffered.
Previously, the code to make debug output unbuffered applied only if
debugging to a file, not if debugging to stdout or stderr. Making
stdout line buffered when debugging was suggested by Steven Bellovin.
bmake_malloc and friends. Implement them via macros for the native case
and provide fallback implementations otherwise. Avoid polluting the
namespace by not defining enomem globally. Don't bother to provide
strdup and strndup, they were only used for the estrdup and estrndup
comapt code.
This addresses the presence of emalloc in system libraries on A/UX and
resulted strange issues as reported by Timothy E. Larson.
rare and skipping over normal characters with strcspn is therefore
faster. Further simplify logic by always setting newline and precompute
the size of the string.
OK christos@
.if empty xxx(foo)
which are interpreted as
.if empty(foo)
or
.if empty (foo)
This is based on rillig's commit to pkgsrc/devel/bmake, but doesn't warn
for the third case. Discussed with sjg.
to override the default shell:
* Rename _BASENAME_DEFSHELL to DEFSHELL_CUSTOM, because it's no longer
always a basename, it might be a full path;
* Rename DEFSHELL to DEFSHELL_INDEX, because it's actually an index into
an array;
* Provide symbolic names for the possible values if DEFSHELL_INDEX;
* Document how the build environment may set DEFSHELL_INDEX or
DEFSHELL_CUSTOM to choose the default shell;
* Move the fallback definition of DEFSHELL_INDEX from config.h to job.c,
because it's used only in job.c.

against the directory name of the makefile being processed.
Shortens a lot of pathnames (especially in pkgsrc) and significantly
reduces the number of duplicate entries in .MAKE.MAKEFILES
are first processed, not for every line of every loop inside the file.
When (attempting) to check for duplicate names, use the spaces between names
as separators rather than using strstr() - which is slow and wont find
duplicates after an incorect early match.
However the duplicate check is rather broken (especially for pkgsrc) where
names like ../../devel/atk/../../devel/glib2/../../devel/gettext-lib/ \
../../devel/gettext-lib/../../mk/buildlink3/../../mk/bsd.prefs.mk
which need (some form of) realpath() processing.
'cd pkgsrc/xaa/gtk2; make show-var VARNAME=.MAKE.MAKEFILES' shows the problem.
