[PATCH CVS] skip OS/2 system install

[Ilya Zakharevich]

This patch should make search for install program skip the
x:\OS\INSTALL\install.exe program.  But I'm not sure that I put a
correct number of \\ in the file.  The number-of-\\ below works inside
configure script; mayb they need to be duplicated (twice?) inside m4
files?  I cannot check it now - autoconf will not build itself yet.

Enjoy,
Ilya
