* toplev.c: Don't include setjmp.h. Kill float_handler_set,
float_handled, float_handler, float_signal, set_float_handler,
and do_float_handler. Set handler for SIGFPE to crash_signal.
* toplev.h: Don't prototype do_float_handler.
* c-lex.c: Fold parse_float into lex_number. Make warning
about portability of hex float constants more informative, and
don't issue it on top of a syntax error.
* fold-const.c: Fold const_binop_1 and fold_convert_1 into
their callers.
* real.h: Define REAL_VALUE_ABS here...
* simplify-rtx.c: ... not here. Fold check_fold_consts,
simplify_unary_real, simplify_binary_real, and
simplify_binary_is2orm1 into their callers.
* tree.c: Fold build_real_from_int_cst_1 into caller.
* doc/tm.texi: Document REAL_VALUE_ABS and REAL_VALUE_NEGATIVE.
* tsystem.h: Include float.h here...
* libgcc2.c: ... not here.
java:
* lex.c: Change java_perform_atof to take normal parameters
instead of a pointer to a parameter block. Call it directly
from java_lex.
testsuite:
* gcc.dg/c90-hexfloat-1.c: Adjust error regexps.
