>Description:

When ABI is set to '32' in /etc/mk.conf, transform_mipspro_cc adds "-n32" to CFLAGS.

However, in the gmp-4.2.2 package's Makefile is the conditional:

.if ${OPSYS} == "IRIX" && !empty(ABI)
ABI= o32
.endif

... which results in the compiler being passed "-n32" (from my default CFLAGS) and "-o32" (from transform_mipspro_cc) - which causes the compiler to abort with an error.

Surely, the check should be for 'empty(ABI)' rather than '!empty(ABI)' - why redefine the ABI to be different to every other package on the system (something which the bootstrap README expressly forbades), but only if it *is* already set?
>How-To-Repeat:

gmp's config.log contains:

>Fix:

Changing the sense of the conditional actually results in:

configure: error: ABI=32 is not among the following valid choices: n32 64 o32
*** Error code 1

... so gmp's configure's use of the variable ABI is at odds with the pkgsrc convention of using '32' as the ABI value for 'n32' binaries.

This should be patched and fixed - because this package is actually impossible to compile: If the value of ABI is changed to 'n32' (as the package expects) then transform-mipspro-cc rejects it.

I have got gmp to compile successfully with the following patches:

I'm not sure why the last two should be required, and someone with more skill than me should probably take a look in order to fix these properly... in both cases (va_list and uint_least32_t), the code won't compile without the extra definitions but complain about them being multiply defined if included as above!
