Thanks.

Maybe I'm missing something, but where is the fallback, exactly?  If
command extensions are not available, then what will be the value of
fusercflags after this line:

 +set fusercflags=%usercflags:"=\"%

and how will be that value handled by the rest of the batch file?  All
I see is that you use that value to append a line to config.h, like
this:

 +if (%docflags%) == (Y) echo #define USER_CFLAGS " %fusercflags%">>config.tmp

What am I missing?
