* invoke.texi: Add -mlong32 documentation.
* config/mips/mips.h (mips_explicit_type_size_string): New.
(TARGET_SWITCHES): Add 'long32'.
(TARGET_OPTIONS): Add 'explicit-type-size'.
(CC1_SPECS): Set -mexplicit-type-size.
(LONG_MAX_SPEC): Change a use of 'no-long64' to 'long32'.
* config/mips/abi64.h (LONG_MAX_SPEC): Same. Add 'mabi=32'.
* config/mips/mips.c (mips_explicit_type_size_string): New.
(override_options): Use it.
* config/mips/osfrose.h (CC1_SPECS): Set -mexplicit-type-size.
* config/mips/mips.h (SUBTARGET_CPP_SIZE_SPEC):
Pointer size now depends on both size longs and size of GP
registers.
