Compile Gnu m4 with OpenSparc's GCC Problem

[lys014]

I am a newbie in Solaris. I try to install Gnu m4 in my Solaris 10. But i
encountered some warnings when i compile it with opensparc's gcc. 
Q1) Is it beacuse Gnu product is not compatible with opensparc compiler?
Q2) Can someone help me to sort it out?

Below is the warnings i received during compiling Gnu m4.
--------------------------
regex.c: In function 're_match_2_internal':
