typo in gcc/configure?

[Dietmar Schindler]

GCC version 2.95.2
host m68k-hp-hpux9.03

Dear GCC maintainers,

in gcc/configure there are about 20 occurences of the file name
"xm-alloca.h", which can be found in gcc/config, and 3 occurences of the
file name "xm_alloca.h", which can be found nowhere. Making gcc fails
for this reason. I think the '_' is a typo. Am I right?
