Yes. ;-)

Gcc has a bug with ASM statements which cause to compile wrongly
defined ASM statements correctly. However, in egcs this bug isn't anymore
but most ASM statements in existing programms are not correct so egcs will
fail to compile them.
I'm not sure if the ASM statements in gnupg are fixed or not. But I think
they aren't which will result in this problems. I don't know much about
this issue but I think the problem domain is called `register clobbing' or

As a solution you may try to use `--disable-asm' when you configure gnupg.
I don't know if this help.
