RE: Build macro not to search for sh.exe or bash.exe

[David Baird]

I've made some simple modifications to main.c to resolve the issue I
found.

Platform: Windows 32-bit compiled with Visual C++


Problem: Setting SHELL to cmd.exe has no positive effect on running make
commands.
Solution: Changes to main.c to recognize that SHELL=cmd.exe setting in
make file should behave as if no SHELL was set, and no sh.exe was found.
All commands should be run in batch file mode with the native Windows
command shell.

Patch to main.c (differences from latest 3.81 sources in CVS)

Problem: When running with native Windows command shell, the "Path"
variable is the valid variable for defining the path. Make automatically
copies the "Path" variable to a "PATH" variable, but never maintains it
when "Path" changes in the make file.
Solution: The PATH variable should not be set in main.c. It is
unexpected. Only the Path variable should be used for the native Windows
shell.
