Linux gcc compiling error
« on: September 26, 2004, 07:51:55 AM »
Compiling nasm 0.98.38 sources on Slackware 10.0, kernel 2.6.7, I come up with some errors that keep Make from working correctly. Does anyone know what might be causing this? The error messages are:

ldrdf.c:1154: warning: string length `516' is greater than the length `509' ISO C89 compilers are required to support

and:

rdoff.c:96: warning: dereferencing type-punned pointer will break strict-aliasing rules

Here are the full outputs of ./configure and make:
