its windows based. (i am running W2K, and i tried it on a XP machine too). 
at first the problem occured with m4 1.4 and cygwin1.dll from Cygnus 1.1.7.

i have one environment and i switch just m4.exe from 1.4.0 to 1.4.4. and the
problem is gone.

i am using:

S:\TOOLS\C>where cygwin1.dll
25.02.02 18:16  769352 E:\LcDevInst\BIN\cygwin1.dll

this is a copy from:

 Verzeichnis von C:\apps\lc32env\lc32dev\Cygnus\1.1.7\bin

25.02.2002  18:16              769.352 cygwin1.dll

i just have the required binaries m4.exe and cygwin1 copied to my machine. 

a few days ago i installed MSYS1.0 and tried it in this environment with the
same result.

note: the mount command says:

C:\apps>where mount.exe
25.02.02 18:16  10240 T:\lc32dev\Cygnus\1.1.7\bin\mount.exe

C:\apps>mount
e:\temp on /tmp type user (textmode)
