Bonjour,
voilà ce que donne pour moi le début de mon ./configure:
Detected operating system: Linux
Detected host architecture: i386
Checking for cc version ... 3.3.3, ok
Checking for host cc ... cc
Checking for CPU vendor ... AuthenticAMD (6:8:1)
Checking for CPU type ... AMD Athlon(tm) XP 2400+
Checking for GCC & CPU optimization abilities ... athlon-4
Checking for kernel support of mmx ... yes
Checking for kernel support of mmx2 ... yes
Checking for kernel support of 3dnow ... yes
Checking for kernel support of 3dnowex ... yes
Checking for kernel support of sse ... yes
Checking for mtrr support ... yes |
et au résumé:
Byte order: little-endian
Optimizing for: athlon-4 mmx mmx2 3dnow 3dnowex sse mtrr |
quand je commence la compil':

tu remarqueras que dans le gcc on a les flags "-march=athlon-4 -mcpu=athlon-4" et au départ j'ai bien i386... donc c'est normal
