Hello,

when I run the attached example by calling make I get the following error
message:

make[1]: Entering directory `/home/herb_jo/maketest'
make[2]: Entering directory `/home/herb_jo/maketest'
make[3]: Entering directory `/home/herb_jo/maketest'
make[4]: Entering directory `/home/herb_jo/maketest'
make[5]: Entering directory `/home/herb_jo/maketest'

make[1]: *** [all] Error 2
make[1]: Leaving directory `/home/herb_jo/maketest'
make: *** [all] Error 2

If I change the variable TARGETS in the file "Makefile" the "Resource
temporarily unavailable" error is sometimes replaced by 

make[5]: execvp: /bin/sh.exe: Invalid argument

Under a certain threshold no error occurs.

I think this could be an error in the implementation of execvp in cygwin. I
tried tracing the error and ended at a call to _go32_dpmi_simulate_int(0x21,
&r) in cygwin-1.3.2-1/newlib/libc/sys/go32/exec.c. I am not shure whats going
on here.

My version of make is:
GNU Make version 3.79.1, by Richard Stallman and Roland McGrath.

My version of cygwin:
 >uname -a
CYGWIN_NT-4.0 MU0A2057 1.3.2(0.39/3/2) 2001-05-20 23:28 i686 unknown

The same Makefiles are working as expected with linux.

Thank you for your help

Bye,
Joachim
