PATH doesn't reach cygwin/dos environment

[Gabriel Zachmann]

gmake behaves very strange when I try to export the variable PATH
to the environment.
(I live under Cygwin 1.1.4 right now with gmake 3.79)

Consider the following makefile:

--- makefile
    #!gmake -R

    SHELL := /bin/bash --noprofile --norc

    #export PATH := blub
    #export PATH := $(shell cygpath -w -p "$(WIN_PATHk")
    #export PATH := $(shell cygpath -w -p 
"$(WIN_PATH):$(MSVC_DIR)/VC98/Bin:$(MSVC_DIR)/Common/MSDev98/Bin")

    export QQ := $(shell cygpath -w -p 
"$(WIN_PATH):$(MSVC_DIR)/VC98/Bin:$(MSVC_DIR)/Common/MSDev98/Bin")

    q:
            set
    .PHONY: q
--- makefile

The following is the output from 'make q':

    set

WIN_PATH=/cygdrive/d/WINNT/system32:/cygdrive/d/WINNT:/cygdrive/d/WINNT/System32
    /Wbem
    _=/bin/bash

Note the value of variable QQ and PATH.
Now, when the first 'export PATH' line in the mkaefile is active,
the value of PATH in the environment of the 'set' command is
    PATH=blub
which is what I expected.

When the second line of 'expotr PATH' is active, I get
    PATH=d:/WINNT/system32:d:/WINNT:d:/WINNT/System32/Wbem
which is still almost what I expected.
The bug here is that the directories are not separated by ;!

When the third line of 'export PATH' is active, I get
    PATH='/usr/local/bin:/usr/bin:/usr/bin:/cygdrive/d/WINNT/system?'
which is completely wrong!
It seems to be the original value as set by bash.
I suspect, that the PATH exported from gmake to bash is bogus (note the ?
at the end of PATH), and then bash decides to use its default.

Anyway, what am I doing wrong?
Is there a bug in gmake?

Confused,
Gab.
