>Description:
Compilation fails with the following error message:

m4  crypto/des/asm/des_enc.m4 > crypto/des/des_enc-sparc.S

m4:crypto/des/asm/des_enc.m4:426 more than 4096 chars of argument text

>How-To-Repeat:

>Fix:
As a workaround, you can simply add `-B8192` as an option to m4 and run the command by hand, then continue the pkgsrc build.

I'm not sure whether there is a way to pass this option through the pkgsrc framework, so I don't have a patch.

Another option might be to add devel/m4 as a dependency on Solaris?  I haven't tried this, but I assume GNU m4 doesn't have the same limitation.
