Subject: am7xxx: bump _POSIX_C_SOURCE to 200112L for lroundf()
X-Git-Tag: v0.1.7~46
X-Git-Url: https://git.ao2.it/libam7xxx.git/commitdiff_plain/80f9d332324848b878fca92f7097aa8fb71ec423?hp=0fe6736d63a0f869ba3abe509225ffdb044de19d

am7xxx: bump _POSIX_C_SOURCE to 200112L for lroundf()

The library code uses lroundf() from math.h but some compilers may warn
about an implicit definition of it, so make sure it it actually
available by following the requirements from the LROUND(3) man page.
