INTEGRATION: CWS dmake43p01 (1.5.2); FILE MERGED

2006/02/26 23:33:37 vq 1.5.2.11: #i62118# Fix invalid detection of circular dependencies arising from F_VISITED
and F_USED both having the same value but being used in different contexts.
2006/02/02 04:50:08 vq 1.5.2.10: #i47919# Fix typo.
2006/02/02 04:39:55 vq 1.5.2.9: #i47919# Use the correct handler function for the signal() handling.
2006/02/01 23:28:54 vq 1.5.2.8: #i60948# Add -m option family to generate timing information for targets
and/or recipes. (Autotools files were regenerated.)
2005/09/05 20:56:44 vq 1.5.2.7: #i53148# Move redirection of stdout from parent to child and avoid
capturing spurious output from other process queues.
2005/09/05 17:23:44 vq 1.5.2.6: #i53148# Additional patch to make sure that the shell escapes is executed
after all previous recipe lines from the same target have finished.
2005/09/04 19:38:14 vq 1.5.2.5: #i53148# Fix $(shell ...) handling for parallel builds with MAXPROCESS > 1.
This certainly includes the -P# switch with # > 1.
2005/05/05 21:45:39 vq 1.5.2.4: Issue number: 38830
Submitted by: waratah@openoffice.org
Change dmake's diagnosic output to use "Warning:" or "Error:". Adding the
colon makes it easier grep for these diagnostics in long logfiles.
2005/04/22 01:04:35 vq 1.5.2.3: #i47851# Increase the version number to 4.4-cvs and slightly rearrange the
output of "dmake -V".
Remove the hardcoded (in autotools builds) OS macro. It had the wrong value
to be usable with the startup/*.mk and is not mentioned in the man page.
Clean up configure.in and friends.
2005/04/11 03:28:54 vq 1.5.2.2: #i43252# Introduce the macro ABSMAKECMD that's value for a native Windows
dmake executable (compiled with MS Visual C++ or MinGW) is the absolute
filename and NULL for other operating systems or dmake build with other
compilers.
If DMAKEROOT is not changed and only for native Windows dmake versions the
value of DMAKEROOT now defaults to "$(ABSMAKECMD:d)startup".
2005/04/09 21:22:30 vq 1.5.2.1: #i43254# Make the usage of DMAKEROOT consistent with the man page for
all OSs. This includes the removal of "SOLARVER UPD INPATH OS UPDMINOREXT"
from the list of macros that are always imported from the environment.
Patch inspired in part by shay@openoffice.org.
