PATCH: makes pj backend compile again.

[Steve Chamberlain]

This patch makes the picoJava backend compile again.

2000-02-28  Steve Chamberlain  <sac@pobox.com>

	* pj.c (pj_expand_prologue): current_function->args_info is
	now current_function_args_info.  

	* pj.h (STORE_FLAG_VALUE, USER_LABEL_PREFIX,
	LOCAL_LABEL_PREFIX, ASM_GENERATE_INTERNAL_LABEL,
	ASM_OUTPUT_INTERNAL_LABEL, ASM_OUTPUT_SKIP): Define.
