# Note: Making the distdir target in the Makefile.in files, genereated
# by automake, can cause two kinds of problems on cygwin.
# Both problems are fixed below by modifying the Makefile.in files.
#
#### Problem 1
#
# The first problem is that if $(DISTFILES) is too big (around 30502
# bytes on my system), the make aborts with the following error:
#
# mkdir -p -- ../../Coin-2.2.0a/src/elements/../../include/Inventor/elements
# c:\cygwin\bin\bash.exe: *** fork: can't reserve memory for stack 0x40000 -
# 0x240000, Win32 error 487
#      4 [main] bash 2220 sync_with_child: child 3112(0x6DC) died before
#        initialization with status code 0x1
#    438 [main] bash 2220 sync_with_child: *** child state waiting for
#        longjmp
# /bin/bash: fork: Resource temporarily unavailable
# make[2]: *** [distdir] Error 128
#
#
# Simplified case:
# The following command line will fail with the error message mantioned 
# above:
#
# [1]
# list='$(somevar)'; foo=`pwd`
#
# If I rewrite the line to (note change of quoting) :
#
# [2]
# list='$(somevar)'; foo='pwd'
#
# list is set correctly, but foo, of course, isn't.
#
# If I replace this with the following, everything is OK (note the
# non-existent semicollon on the first line)
#
# [3]
# echo $(somevar) > somevar.txt
# list=`cat somevar.txt`; foo=`pwd`
#
#  This was the only fix I was able to come up with. I do not know why
# [1] fails and [2] doesn't. I think it has to do with the maximum
# command line size for bash when bash forks a sub-process. The first
# error message comes from <cygwin-source>/winsup/cygwin/dcrt0.cc,
# called from fork.c.
#
# A similar bug report can be found here:
# http://savannah.gnu.org/bugs/?func=detailbug&bug_id=3467&group_id=353
#
#
# And another one (with a suggested solution):
# http://www.cs.mu.oz.au/research/mercury/mailing-lists/mercury-reviews/mercury-reviews.0202/0162.html
#
# The fix will be removed when we've start using makefiles in the include
# directories.
#
#### problem 2
#
# The dist target in Makefile.in, generated by automake, is incompatible with
# filesystems mounted in textmode under cygwin. A slight rewrite of the
# offending line fixes the problem:
#
# Change
#
#   $(AMTAR) chof - $(distdir) | GZIP=$(GZIP_ENV) gzip -c >$(distdir).tar.gz
#
# into
#
#   GZIP=$(GZIP_ENV) $(AMTAR) czhof $(distdir).tar.gz $(distdir)
#
# Alternative fixes
# - Abort make process if source directory is mounted in textmode
# - Let the makefile mount the source directory in binary mode
# - Try to convince the automake guys to change automake
#   (this will probably fail, see note in 
#    autotool/devel/share/automake-1.7/am/distdir.am regarding this)
