>Environment:
System: IRIX64 halo 6.5 6.5.29m 01090133 IP30
Architecture: mips
Machine: IP30
>Description:
While compiling libwww I found that it tries to pass -Wp,-MD,somedepfile to
the compiler, this gets just passed through and causes mipspro to think
it should compile somedepfile (-MD is not a valid option and does not accept
an argument) which does not exist and the build breaks.
>How-To-Repeat:
Try to build libwww on IRIX with MIPSPro (7.4.4)
>Fix:
The following patch will solve the issue. Note: this does create a depfile, and
some other pkg may incorrectly assume that the depfile is in a gnu-like format
and potentially break. I have not come across such a pkg.
