  Yes.  The TARGET_OS comparison for "pe" uses "strncmp" already.  So,

gas/ChangeLog
2008-05-07  Chao-ying Fu  <fu@mips.com>

	* config/tc-mips.c (md_begin): Use strncmp to compare TARGET_OS, in
	case that some characters append at the end of the name.
	(mips_ip): Likewise.
	(s_change_sec): Likewise.
	(md_section_align): Likewise.
