	* varasm.c (default_exception_section): Move to...
	* except.c (default_exception_section): ... here. Make
	.gcc_except_table read-only if it is not expected to have any
	dynamic relocations and linker handles it.
	* dwarf2out.c (default_eh_frame_section): Make .eh_frame read-only
	if it is not expected to have any dynamic relocations and linker
	handles it.
	* configure.in (HAVE_LD_RO_RW_SECTION_MIXING): Check what ld does
	when linking read-only and read-write sections together.
	* configure, config.in: Rebuilt.
	* crtstuff.c (EH_FRAME_SECTION_CONST): Define.
	(__EH_FRAME_BEGIN__, __FRAME_END__): Add it.

is not portable.


On Solaris 2.5.1, 2.6, 2.7:
checking linker read-only and read-write section mixing... ld: fatal: option -h and building a dynamic executable are incompatible
ld: fatal: Flags processing errors

'-shared' is not supported by Sun ld.


On Solaris 2.8, 2.9:
checking linker read-only and read-write section mixing... /usr/ccs/bin/as: "conftest1.s", line 1: error: statement syntax

'.section "myfoosect", "a"' is not supported by Sun as.
>How-To-Repeat:
Configure the compiler on the aforementioned Solaris versions with Sun tools.
>Fix:
Disable the check on non-Dwarf2 platforms?
