I am sorry to see that you are obviously a not interested in a reply
as you did remove comp.unix.solaris which is the only group I read.
For this reason, I needed to "fix" (restore) the list of newgroup to the
original value.

Let me first point to the real problems:
- Backshlash handling is completely broken in the gmake makefile parser.
GNU make is trying to work around the problems caused by the
proken parser by adding dozens of #ifdef WIN32 constructs.
A parser that follows the POSIX standard does not need a single
line od DOS/Win32 specific code.
- Space handling (e.g. escaped newlines) is completely broken in
the gmake makefile parser.
Use this Makefile:
FOO=a\
\
\
\
b
all:
@echo "${FOO}"
Test with Sun make, smake (ftp://ftp.berlios.de/pub/smake/alpha/)
and gmake:
\make
a b
smake
a b
gmake
a b
- GNU make incorrectly expands "$<" for non-inplicit rules.
It is impossible to expand "$<" to something useful in
explicit rules.
The fact that GNU make expands it to something strange
causes many people to write broken Makefiles that depend
on the GNU make bugs.
- GNU make incorrectly expands "$*" for non-inplicit rules.
It is impossible to expand "$*" to something useful in
explicit rules.
The fact that GNU make expands it to something strange
causes many people to write broken Makefiles that depend
on the GNU make bugs.

The text shows how up to date many GNU programs are today :-(
The recent standard is POSIX.1-2002.
If you look at the text from the URL you quoted, you will find that the text
does not match GNU make reality.
