Compiling for transistor tester - 1.34m

Have never compiled anything before, use ladyadas guide to install 
winavr.

I get the following when i try to 'make'...

H:\Electronics\ComponentTester-1.34m>make
      0 [main] sh 228 sync_with_child: child 14724(0x1B8) died before 
initialization with status code 0xC0000142
     91 [main] sh 228 sync_with_child: *** child state waiting for 
longjmp
/usr/bin/sh: fork: Resource temporarily unavailable

-MT main.o -MF dep/main.o.d -c main.c
main.c:1886: fatal error: opening dependency file dep/main.o.d: No such 
file or directory
compilation terminated.
make: *** [main.o] Error 1



..... Any ideas where i might be going wrong?

googling "/usr/bin/sh: fork: Resource temporarily unavailable" mentions 
issues with something running in windows Vista, i'm on Win10 if it makes 
any difference.

Any assistance appreciated.
