Description
Hi/2.
When I did 'make check' with automake v1.13.1, gawk failed because it could not open pipe.
I looked into gawk sources, then found that the failed function was popen(). And popen(), maybe system() as well, failed that COMSPEC and OS2_SHELL were NULL. Looking into more, I could know that a root of this problem was spawnvpe() in make, which is compiled by kLIBC.
envp argument included COMSPEC and OS2_SHELL correctly. Nevertheless a child did not inherit them.
I don't know which conditions trigger this. But this occurs whenever 'make check' with automake v1.13.1.
Fortunately, there is simple workaround. It is to set EMXSHELL. EMXSHELL does not disappear.
