Problems with gnu make

I am running a make file through the gnu make tool and i am getting the following error

jsh1035c:/users/egate453/admegate/kapil/samples $ make -f GNUmakefile queue_c
make -f ./GNUmakefile queue_c in_objdir=1 build_root=/users/egate453/admegate/kapil/samples
make[1]: Entering directory `/export/home/users/egate453/admegate/kapil/samples'
gnu-sparc-solaris2.8 -c -o queue_c.o queue_c.c
make[1]: gnu-sparc-solaris2.8: Command not found
make[1]: *** [queue_c.o] Error 127
make[1]: Leaving directory `/export/home/users/egate453/admegate/kapil/samples'
make: *** [queue_c] Error 2

Anyone know what 'gnu-sparc-solaris2.8' is?

attach that make file please, otherwise nobody could help

i've sorted out the problem by setting the RCMPLR variable to gcc before calling make.
