CVS compile problems

[Petter Sundlöf <petter sundlof findus dhs org>]

Hi. 1.2.1 compiled fine for me, but for some odd reason I am getting an
error with CVS. GCC 2.95.3, GLIBC 2.2.3. CVS from Oct 22, 16:00 GMT+1.

The error:

make[4]: Entering directory `/home/odd/NL/balsa/libmutt/imap'
gcc -DSHAREDIR=\"/usr/local/share\" -DSYSCONFDIR=\"/usr/local/etc\"

Any help would be appreciated.
